i have been trying to make 3d printed yoyos, it’s really hard especially since I’m using tinker CAD so i have to center everything perfectly. maybe you guys can show me how you do the bearing seating.
i know that @wayne927 has some pretty interesting solutions.

Yeah it is layered plastic… happens 
. Just print a new one NP
Looking at the design I guess your weight distribution will not spin so well since it is very even. But give it a try. I made hundreds till I was satisfied
3D printing yo-yo is fascinating to me. I noticed different materials used between the hub and seat. Is that to leverage material property differences or for easy part swapping?

Right it is both. I printed the seats out of a harder material. And yes they are swappable to use C and D and also if one breaks you just replace the seat.
If you don’t mind me prying what materials did you find work well for the hub and bearing seat? PETG or ASA for bearing seat? Hub PLA?

I mean it does not really matter tbh. This is PLA shells and ABS seats. But it is just gimmicky…
