Yoyo

thingiverse

This yoyo works quite well. Shiny surfaces touching the string make it more efficient than wooden toys. With less energy loss it can roll almost forever! How to assemble? Use thin, strong synthetic string. Make figure 8 and a self tightening loop to make it not slip when the toy rotates. You can put a drop of oil on it. and the sides of the gap. The inside pin can be superglued, or use bluetack, chewing gum, or just press it firmly to make it stay put. Print Settings Resolution: 0.2mm Infill: 25% Notes: Print each side laying flat separately and the pin standing. (= 3 objects to print). You can separate the two halves in Cura, or I can put separate .STL files on request! The holes in the side wall are to put metal screws or lead balls into to make it heavier. It's to make it spin slower and longer. Works well without it thou!
