18650/21700 Protected Li-Ion Cell Battery Case

27 Nov 2024 Edit: This wasn't quite tall enough for a pair of protected cells I ordered; I'll make an edit to these models to make them taller once I've done a little more testing.

An awesome minimal 18650/21700 Lithium Cell holder by @TechAddict_275609 , remixed to add a recess for button-top cells, and 1mm of height for the additional height of a protection circuit board on the cells.

Print 2 of either model and glue 4 6mm x 3mm magnets using epoxy or superglue. Make sure magnets are in correct polarity before gluing or they will repel each other (I recommend printing your opposite polarity cases in mixed colors; e.g. North in one color and South in another, so you don't get them mixed up) .
