My son loves his Beyblades. But he wanted some custom designs and he wanted to modify his existing Beyblades. So I designed a compatible set of parts that can interlock with all his existing Beyblades. We have even printed some replacement parts for his official ones that have been damaged from battling.

Very little support is required to print the top. The only tricky part is you need two small screws and a spring to be able to assemble the base. I had old springs and screws from items and toys that I have taken apart over the years (I hold on to too much stuff). I don't know the sizes because they came out of my junk bin, but a trip to a local hardware store should get you pretty close.

I have include the native Solidworks files, as well as conversions into Step, X_T, Fusion360, STL, and 3MF. I also create a Minimal assembly with only the basic geometry of the interlocking pieces. This version should make it easier to use as a starting point for your own remixes.

Hopefully you can use these files as a jumping off point for your own designs.
