Rim/Wheel - Stepper Feeder

I designed this one as a Stepper visualizer / feeder

It is a very close fitting, you might scale it up a bit or just use a small file to make it fit

make sure to enable thin wall printing, because some of the middle wall really are just one line

my idea was to print it with supports so that the surface won't be "damaged" by my printbed

I will work on some other designs soon
