Yoyo

thingiverse

This yoyo works incredibly well. Smooth surfaces rubbing against the string make it outperform wooden toys hands down. With minimal energy loss, it can roll nearly indefinitely! How to assemble? Use a thin yet incredibly strong synthetic string. Create a figure eight and a self-tightening loop to prevent it from slipping when the toy rotates. You can add a drop of oil on it and the sides of the gap. The inside pin can be superglued, or use bluetack, chewing gum, or press it firmly in place to keep it from shifting. Print Settings Resolution: 0.2mm Infill: 25% Notes: Print each side flat on its own and with the pin standing upright (= 3 objects to print). You can separate the two halves using Cura, or I'd be happy to provide separate .STL files upon request! The holes in the side wall are designed for metal screws or lead balls to make it heavier. This slows down the spin time and prolongs its duration. Still works fantastically without it though!
