STEM Gears Fidget Learning Toy Set

This is my design of a STEM learning toy with gears, moveable parts, and a storage case. Someone proposed the idea that we don't have enough STEM learning tools in the 3D printing community yet, so myself and a few others working on their own designs, decided to make some fun sets.

I sized this for printing on the A1 Mini (pieces are all scaled at 81% should you be using just the STLs). No supports needed.
