Yo-Yo with 608zz Bearing

Still in development — currently testing balance, spin time, and bearing setup.

Hardware required:

• 1x 607ZZ bearing
• 1x M3x10mm countersunk screw
• 1x M3 nut

A minimalist 3D printable yo-yo featuring deep conical side profiles, chamfered edges, and a clean symmetrical design.

Uses a standard 607ZZ bearing with an M3x10mm countersunk screw and M3 nut for assembly.

Design complete — currently in functional testing and optimization phase. Testing focuses on balance, spin stability, and print tolerances before final release.

Optimized for FDM printing with clean outer surfaces and an easy-to-assemble structure.

The print profile uses an outer infill of 60% to add weight and increase rotation, and an inner infill of 15%.
