Summary

Cute round little potion bottle d4s for rolling healing potions in tabletop role playing games like D&D. Wanted bigger healing potion dice that felt more like rounded glass bottles. These bottles are sized 16mmx16mm in the XY direction, and they feel like they fit in next to the normal sized polyhedral dice. I printed these in red PLA with a 50 degree support angle with a close, dense interface for firm attachment to the small support, because of the tiny contact area. I also blocked supports on the numbers and cleaned up the sag by hand. Use a very high infill for a solid feel. I tried 50% and I wish I had gone higher.  A filament swap at the height of the cork would be pretty easy, even without multicolor printing. Use a highly thinned gloss acrylic paint or nail polish for numbers. Would look amazing printed in clear red resin.

A version with a flatter bottom would print far more easily and with less cleanup, but I didn't want to worry about the chance of the die landing on an invalid result by landing upright. I'd be curious if anyone decides to slice the bottom off of these before printing.
