This is remixed from these soucres: Spiralized Gridfinity Bins and Gridfinity - Vase Mode

I liked the spiralized gridfinity bin, but it's pretty flimsy and doesn't stack super well, and the reinforced one does not have places for magnets.

This combines both models into a reinforced bin with magnet slots, aka the best of both worlds

I also added reinforcements to the top lip because I had issues with it cracking when stacking heavy things

Ultimate version should be printable with .4mm and .6mm nozzles

This holds just over 2 fl oz with head room to stack more bins

It's not waterproof by default but you're welcome to experiment
