fidget spinner

thingiverse

This is a fidget spinner. It can be made from the STL file with a bit of intervention. First, all the coordinates for the STL file should be doubled in the slicer. Second, the holes in the gears are meant to be 4mm in diameter, on my printer a quick scarf with a 4mm drill was needed. I have been making it without 100% infil but I would recommend the higher number to give it more strength, otherwise the posts could shear off too easily. I tried to upload an MP4 of the operation by my wife but it doesn't seem to want to go. :( The gears were meant as faces for a dodecahedron but fell victim to a bit of fooling around. The gears were made by superimposing on the rim of a circle, a cosine function oscillation. Resolution could be improved for a more important or needed gear system. Enjoy :)
