Summary
This is a basic pulley. It has a 50mm main wheel and will handle up to a 10mm or 3/8″ line. You need two 608 skate bearings, and two 8mm x 35-40mm bolts and nuts. You can either tie a line to the top or use a carabiner as a clip. There are two wheel designs one fancy and one easier to print. I find that the wheels print well in the standing position with support. If you have problems printing that way the simpler design can be printed on its side. I may include a no bearing wheel very soon. The sides should be printed flat with 30% or more infill. I used 2mm walls, top and bottom with 30% infill. That basically makes the sides 100% with a little infill around the top block. There will be more variants, so stay tuned.
Enjoy.
If you like my designs why not tip me a dollar or two. Your support will allow me to spend more time on these designs and their variations. Thanks!

Summary
Modified for the 608 bearing. Changed the 2 pulleys to one pulley, and added .1 to the inner diameter, and swapped out the toothed pulley for deeper toothed one (by Grimlock_UK).

This is just a little spinner I designed. I think the tolerance I used is a little much So I advise scaling this down very slightly. enjoy!

608 Bearing Fit Test 3D Print Model
Summary
This is my test for 608 (repeat… “608” bearings. I had a typo of “609” that is in the filename.) I used it to calibrate my printer so that the hole fits a 608 bearing with a press-fit. You can also compute a multiplier for scaling a fidget spinner with this. Hope it helps.

Fidget Spinner – 608 Bearing Cap 3D Print Model
Summary
I designed this end cap to be able to remove them without breaking them. I have printed a dozen in every color I have, and the neighborhood kids love to swap them in and out for the spinners we print, as well as the ones they buy or trade for with friends. Not much to it, but they like the variety of colors.
Tip for printing… don’t just print 1 at a time. Print at least 4. This allows the thin layers at top to cool while the printer moves to the next piece. I do 12 at a time, and have a bowl full now.
