Pokemon Curveball Template for Samsung Galaxy S6 3D Print Model
Summary
This is a simple template to assist in throwing a curveball ( or strait ) in the Pokemon Go App. It is a layover design so that it will not interfere with your current Samsung Galaxy S6 case or battery pack. Also being thin, it travels easy in your pocket or purse.
While this was designed for the Samsung Galaxy S6, It seems to work well with other phones of similar size.
View the YouTube video to see it used in action here:https://youtu.be/YHFHvWAEmQc
This video was shot for the iphone template, however the principals are still the same.

GoPro Hero4 Lens Holder 3D Print Model
Summary
This is a lens holder for GoPro Hero4. Its useful if you use custom lenses with your GoPro. I helps keeping the lens in focus so you wont turn it accidentally. You will need one 3mm nut and bolt.
Also, you may want to help the nut with a soldering iron an to sand a little bit the flaps of the holder in order to make it fit perfectly.
Dont turn too hard as you risk to tilt your lens.

Wall Hanger for Master Sword and Hylian Shield 3D Print Model
Summary
I designed a very simple wall hanger for two very helpful tools for combat. I actually made Adafruit’s Hylian Shield (https://www.thingiverse.com/thing:824544) and ChaosCoreTech’s Master Sword Designs (https://www.thingiverse.com/thing:1449187) just for fun, but I thought that hanging the two prints in my room would be cool. So i designed the hanger with the sword being held at a 30 degree angle.
Just a little disclaimer: Currently with my design the shield is drooping down from the top a little bit from what I would like, but nonetheless still looks amazing to have in the room. Mainly I wanted to show this display method can be done: Try this design if you want. I failed to insert a folded notecard to tighten the shield and holder, so I will probably work on making the handle part of the wall hanger tighter in my design.

If you do print this, be wary that this is a work in progress as explained above, and that you probably want a decently strong hanger to support holding both a shield and sword, which requires more plastic to print the infill/ shell thickness. This print also needs “supports” set to everywhere if you use Cura.
Rotate the object so that the “handle holder” part is flush with the bed. Your printer should only print supports for the top of the handle holder. I’m not sure why Solidworks exports STLs in a different orientation when I designed this with the correct positioning.
I felt comfortable having the shell thickness to be 2 mm, and its holding fine. Printed in pla grey plastic with extruder 215 c and bed 60 c -

Tak Piece Cutting Jig 3D Print Model
Summary
This jig is made to use with 1″ square and/or 1-1/8″ round dowel. There is an end stop for a 10mm slice (~3/8″ after sanding), and a spot to place the discs to trip a flat. The second holder is to support the length at a greater distance. There are screw holes for #6 or #8 drywall screws. that can be used to screw it down to a 1×2 or other support.
I have a portable work bench with clamping sections. I made the bottom plates to work with M3 bolts to clamp down on a slot of my workbench which secures it entirely satisfactorily. #6 bolts would likely work just as well. The holes may need to be expanded a bit, but should be tappable.
I printed the jig and support with 3 walls and 15% infill, the clamp plates with 4 walls and 35% infill. -

20$ Tornado(vortex) Generator 3D Print Model
Summary
Background History First
About a month ago.. I was about :the half of my peanut butter toast when my wife mentioned me that my older son has selected his subject for his third grade presentation… Tornado! Seriously! That’s great… That kind of subject spark my interest…
So I went here to find something kick-ass to spice up his presentation, I’ve found a pretty cool tornado vase… So i start printing it… I was looking at my print starting up, finishing my toast (lol)… And my brain was already at the next step… This looks great… But…. It’s so… Passive…
So i went back, and i remembered playing with bottle and tornado coupler when a was a youngster… Great found that one and start the print on another printer… Ok now the bad news… I didn’t drink soft drink so 2L bottle didn’t exist at home… Humm ok, that’s right… You could be surprised what I’m ready to do in the name of science 😉
I went back to ask my wife to buy some 2l bottle fill with any liquid , after giving explanation why i leave the table as…. She agreed to add those to the groceries list…
So i go to work… But you know… My brain was working over that… Traffic jam are a great reason to go in my wonderful alternative reality lol
So I made a great kit… Right?… Great, yes! But not awesome… Need to add some mad scientific stuff…
So I search and didn’t find something that would fill my needs…Tornado + motor = awesome!
So … I fired my freecad!
design details
This as been designed to be affordable as possible… About 20$ and that includes at least 2L of your favorite soft drinks 😉
Basic system need a 5-10$ ultrasonic mist generator 24v, and a 50-60mm 24v centrifugal computer fan and a cheap standard on-off rocker switch …
Since my 24v fan and my cheap PWM pot didn’t find their way to my home in time…I was forced to create that “CSL Editdion” (Chinese Shipping Latency Edition). Currently i use a 60mm 12v fan… Since i was forced to take down the voltage to 24 to 12 v I’ve used an lm317, some resistor and a pot that enable the operator to play with wind speed…
This design as been build with 150x150mm delta in mind… So almost any 3d printer could print that project…
Please Note: This is the first release…. post printing explanation in progress so stay tuned 😉
end of story
So after countless hours of printing and prototyping… I’ve got that working design… Which work really well…
I’m not equipped with professional photographer rig… And droplet of water lighten by led seems to saturate camera sensor… So pictures or video of the tornado are all over exposed… But no issue up to now with human eyes… It looks great if you use your bare eyes to look at it 😉
I’ve holded this design until my kid completed his presentation… You know people with 3d printer have tendency to hide between normal people…lol … Would be a nightmare if other kid in is classroom show up with the same kickass tornado generator… Lol
Be warn: the hardest part of that project was to successfully convince the teacher that my kid designed this by himself… Just joking 😀
Hope it would be useful for you… Also it make a great room humidifier 🙂 -

Zen Meteor 3D Print Model
Summary
First things first:
All credit for the IP of this work goes to Bungie and ActiVision; thank you for giving us this great game.
Next thing:
THIS IS NOT YOUR DAD’S MODEL TRAIN SET. I’ve re-meshed this thing from zilch; from sneezes, air pie, and trodden dreams. It WILL require hand fitment and a robust understanding of construction techniques.
With that out of the way, here it is Fam – Zen Meteor – essentially an anti-material rifle for the gunpowder hedonists in all of us. It is a true 1:1 scale of the weapon in Destiny, and as such imposes several challenges to the would-be builder. As you can see this is a work in progress – I still have to mesh out the scope, and then go through a build iteration and post best practices for assembly. Before I get these out, if you have any questions, please hit me up in PM’s and we can rap there.
CHALLENGE #1: It’s Big.
*** It’s REALLY big. It is also somewhat slender over that length, so there are critical parts and part junctures that NEED a lot of strength. Handling, showing, transporting this thing to and from CONs, cosplay parties, etc, will test its structural integrity. I’ve tried to engineer some good joints into this thing, and have a little more work to do on some pieces to give the design as much engineering cajones as it can possibly have. Also, it will take a LOT of material to print. Lastly, you may notice that the individual pieces themselves are large, too. That is because I have a 300x300x400 build area to work from, and I intend to use the whole thing. I will NOT be re-slicing these things so it can be built on an 200x200x200 printer.
CHALLENGE #2: It’s Long.
*** Building this thing for strength and handling comes at a cost, and that is time. The forend (minus the rails) took 76 hours to print. The receiver takes 100 (when you use the shells and infill that I believe is required. Even if you are more conservative on your shells and infill, I kept the pieces as large as I could to print the biggest assemblies I was able to (so the size alone will still make longer prints than you may be use to). This is primarily due to my leaning toward threaded steel rods through the receiver to join the barrel, forend, and receiver together. Doing this pretty much dictates that building it in halves is a no-go because a tensioned threaded fastener would burst the center seam apart (or it would be trying to). Ultimately, it is going to take so long to sand this thing, prime it, paint it, weather it…and attempt to get it screen accurate…I just accepted the longer print times for the extra robustness it would provide.
CHALLENGE #3: Asssembly.
*** The order in which you build this thing MATTERS, particularly when you get to the gas block, the forward and aft halves of the forend, the rails, barrel, and receiver. Since I’m still tweaking things I DON’T have a definite build strategy though I have some ideas. I’ll post the ‘tried and true’ method when I finalize all stages of assembly, but one thing that is immediately apparent up front is that the rear barrel (the pretty one with all the fluting on it and the sweet taper) will need to be sanded, painted, sealed, weathered, DONE before you put the forend together over it! And before you put the forend together, at very least the insides of the forend will have to be finished So there is a definite order of operations that should be followed – I just haven’t put anything down as gospel yet.
Ultimately, the size of this build alone make it pretty ambitious. Please give feedback with any problems you run into – I’ll try to be responsive about making any changes that need to be made in the files. As an aside, I was considering not releasing this because I like having unique things and benefitting form my work, but the community of makers and the coolness that is 3D printing is why I put all this work out in the first place. So here it is – the thing that I cut my teeth on learning Fusion 360, and breaking in my 3D printer.

My thoughts on this are that shells and infill are lowest out toward the muzzle end, and progressively get denser until you reach the receiver, where they start tapering back again into the buttstock assembly.

Layer Fan Duct for MakerParts 3D printer 3D Print Model
Summary
Fan Duct for the MakerParts 3D printer. This one uses a 50mm Radial Fan. The fan itself has 56.7mm between mounting holes, and the output is a rectangle whose exterior dimensions are 19.3mm x 15mm
This thing works wonderfully, and attaches to the heatsink of the E3D v6. You NEED to place kapton tape around the aluminium block of the extruder, otherwise, the fan will cool it down so much the printer will stop extruding!
With this fan duct installed, i was able to print at 200mm/s with no quality loss at all!

El ventilador radial en sí mismo tiene 56.7mm entre los agujeros de montaje, y la salida de aire tiene 19.3mm x 15mm.
Este ducto funciona maravillosamente, y se sujeta del mismo disipador del hotend E3D v6. Es INDISPENSABLE colocar cinta Kapton (o algún otro aislante térmico) rodeando el bloque de aluminio donde está la punta del hotend, porque sino, al encenderse el ventilador del ducto, la temperatura del hotend cae tanto que es imposible seguir extruyendo!

Animalarm – a sensor to control pet movements 3D Print Model
Summary
A simple but elegant project to create a “pet zone alarm” in your house. It uses infrared motion detectors to sense when a pet (or small child) is moving through a doorway or hall and sends out a loud tone. It does not beep when a (tall) person moves through the same area. With a bit of training animals recognise where they are welcome – without having to use physical gates.
NOTE: WIP – Some electronic component values are subject to change
Post-Printing
Caveats
Obviously, you will need to be able to get the PCB manufactured. The files are all there to do so and it is very cheap. And of course you need the skills and equipment to source and assemble the electronics!
If you want to use a different buzzer, you will need to make your own shell – but the electronics at least will work for you… Application
There is a single trimpot to set the length of the beep, once the alarm is triggered. You can also change component values (C1 in particular) to alter the delay before the alarm goes of before triggering the alarm. Set it longer if the system is triggering falsely.
There are pads in the 3D print design at the top and bottom of the Animalarm. Use double sided tape or bluetack at those locations to mount the alarm on the wall / doorway.
How I Designed This
How this works
The Animalarm uses two PIR (passive infrared) detectors to detect and discriminate between pets and people. The detector needs to be mounted on a door / wall about a meter above the ground. One PIR “looks down”, the other “looks up” to detect motion. A pet only triggers the lower detector and sets of the alarm. If a person is detected, the alarm either never triggers or is shut off.
The circuitry is built around a single CMOS chip and a few transistors – and of course battery, buzzer and PIR detectors. The circuitry is incredibly power efficient, drawing less than 30µW normally and only 10mA when triggered. This means the batteries will probably last a year in normal use… Electronics
The attached files include:
the Eagle design files (schematic and PCB)
Circuit schematic
PCB layers images
Gerber files for the PCB to be produced by seedstudio.com
List of special components and their sources
All the components are incredibly cheap; the PIR detectors are less than $2, the circuit board less than $1; indeed the most expensive component is the buzzer. The total component cost is about $15 (printed shell aside) -

I included a cutout for the cable to exit towards the front, but there is actually enough space for it to go directly to the back between the “legs”, as shown on the pictures.
Post-Printing
After printing, I had to trim a bit the bottom face for the stop to fit in the grove between the cooling fins. Also, the fit was extremely tight; the GoPro mount was really bent at first. After a few days under stress, it looks like the bracket extended a bit and now the fit is perfect.
The model I uploaded has a slightly larger inner diameter and slightly thinner stop, so that should provide an easier fit (although not tested). -

Vacuum Ejector 3D Print Model
Summary
This is a vacuum ejector designed for compressed air to vacuum generation. Advantages of this type of vacuum generation is that it is instant when compressed air is applied it starts generating vacuum. Also, it can handle contaminants in the vacuum flow. As long as the contaminants being ingested in the vacuum port are smaller that the mixing tube diameter (3mm in this case) the ejector will not be blocked.
The input port injects compressed air that is exhausted on the output port. Air in the mixing chamber is entrained in the flow and a vacuum is developed. I have measured 18.5″ of mercury (-9PSI) on the vacuum port with 0 flow. I don’t have a flow gauge so I can’t judge efficiency or flow with an open input.
Graphs with the input pressure and vacuum achieved are attached.
Both the compressed air input and vacuum ports are designed to be tapped with a 1/4″ NPT thread. The wall taper matches the NPT thread and allows easy connection to air fittings.

Using Simplify3d variable thin wall extrusion can help print quality with the fine features. A minimum of 1.6mm wall thickness is needed to avoid the NPT tap from breaking through.
How I Designed This
This design was based of research on steam ejectors and air vacuum generators. There is little useful documentation on the design of these I have found. There were three previous version that did not perform as well (max 5″ of Hg) before I looked at steam ejectors.
The main improvement is the ratio between the expansion tube and the length of the expansion tube. The initial designs had short expansion tubes, but a ratio of 7 for the expansion tube diameter to length greatly improved things.
Since this design tops out at ~75psi, I suspect that I need to look at the mixing tube diameter to prevent supersonic flow. This should improve performance at higher input pressures. -
