Spring Fidget Toy for MMU3 or single material

My grandson liked playing with a springy prototype I gave him so I decided to make a spring toy fidget.

For a simple print the raw shape from Fusion 360 has lots of springiness. I did another with “educational” features using my new MMU3.

The educational features are added in the slicer so the file with PROJECT in the name has those, they are mostly “modifiers” to change color so they don't show up in a geometry only import. The filament shown in white is actually clear in the MMU3 print I did.
