Additional Hardware
This toy requires one 608 skateboard bearing.

Printing
I've included 4 .3mf files prepared for a Prusa Mini+ (Should be easy to reconfigure for whatever bed size you have). Each of these .3mf files can be printed in a different color to recreate the version I've included in the attached images.
Estimated Print Time: 5 hours if you use the included .3mf files (They will fit on a Prusa Mini+)

Recommended Material: PLA
No Supports
Assembly
No tools are required for assembly.
