Yo-yo

thingiverse

This design is based on the memory of a yo-yo I used to own as a kid. And some googling. ###Printed parts 1 x yoyo_top.stl 1 x yoyo_bot.stl 2 x yoyo_mid_gapX.stl Also included (in a zip) are two-piece yo-yos with different gaps. They're tricky prints, but may be worth a try. ###Non-printed parts 1 x 623 ball bearing (3x10x4 mm) 1 x bolt M3*20 1 x nut M3 1 x yo-yo string
