Sunny Spinner toy

thingiverse

This spinner is made for five 0,5" (or 12,7 mm) steel balls, I took mine from a GeoMag toy set that I had lying around. The inner (spherical) radius of the steel ball holders is 13 mm but the opening is exactly 12,7 mm, so including a slight shrinkage of the holder post printing, the balls should be a bit difficult to push into the holder, but once mounted they should have a loose fit. The bearing is a 7x19x6 mm ball bearing (axis x diameter x thickness). I have split the model into three files, to allow you to print each part in a separate colour. Edit: I printed the "sun" piece using PETG, and found it hard to get the surface finish right on the side facing the build plate, so I uploaded a split version. Just use a bit of cyanoacrylate (CA) glue and you have a perfect sun. :)
