Hộp đựng pin CR 2032 hoặc 2016

I use two mini flashlights while backpacking that take CR2016 and CR2032 batteries. I've always wanted an elegant solution to keep them organized and away from potential shorts. I designed it to hold a CR2032 and two CR2016s, but you can use it for any combination of 20mm diameter batteries up to about 3.5mm tall.

Since this model uses a living hinge, I printed it with PETG. Nylon or flexible filament might also be good choices.
