This design is based on the memory of a yo-yo I used to own as a kid. And some googling.
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.
1 x 623 ball bearing (3x10x4 mm)
1 x bolt M3*20
1 x nut M3
1 x yo-yo string
Printer Brand:
Prusa
Printer:
Rafts:
No
Supports:
No
Resolution:
0.1, 0.2 mm
Infill:
100%
Filament: AddNorth PETG Blue, Black
Notes:
The yo-yo in the photo is printed with 100% infill and weighs ~70 grams. If that's too heavy, try printing with less infill, in a pattern that doesn't make it unbalanced.
yoyo_mid_gapX.stl comes in several versions. A wider gap makes it spin better, and a smaller makes it more responsive (1.6 mm is a decent compromise IMHO). This part should be printed with thin layers.
Top fill pattern: Archimedean Chords
The yoyo_mid_gapX.stl parts need to be smooth on top, not to hinder the string. Tip: use a card scraper. Great for removing those little spikes from top layers.
