Summary
The project is a filament holder that attaches to the existing ANET A8 filament holder.
This was inspired by filamentry’s excellent design, TUSH The Ultimate Spool Holder, at https://www.thingiverse.com/thing:2047554, where the filament spool rests on 608 bearings. However the print time for the TUSH was a little longer than I wanted (I’m impatient). Therefore, taking the idea of a bearing filament holder, this design slims it down to just the essentials. It assumes you already have the filament holder provided with the ANET A8. These small holders simply slide onto the existing ANET A8 holder.
The file contains the design for half a holder. You will need two ‘halves’ for each ‘corner’ of the spool, and since there are four corners you’ll need to print eight ‘halves’ total. Glue two halves together with a 608ZZ bearing in between to make one holder. Make four holders total.
I based the design off of my own measurements of the 608ZZ bearings, ANET A8 spool holder, and the spool of filament in my possession. I know there have been some tolerance tweaks to theTUSH, but I haven’t cross-checked the measurements in this design with the TUSH…so your mileage may vary.
If you have the time, print a TUSH. If you’re in a hurry and already have the ANET A8 spool holder, perhaps this is the holder you seek.
