this model is for a 15x5 bearing and 3 6x3 round magnets the middle part does need support.

the bearing is not really functional but it looks cool

there is also a spacer needed for the magnets in the middle part one magnet goes first then the spacer the the last magnet.

if you have a random medium sized bearing laying around you can also use the step model and modify it, or dm me and il edit the model for you.

if you have any questions or need any help feel free to reach out.

added midv2 this is the same middle part but now with slots instead of holes this just makes the first layer easier to print.
