Various battery holders for small batteries. All on 1x1 gridfinity bins. There are versions of each that are stackable or non-stackable … along with magnets or no-magnets.
I printed these all with PLA - usually on a 0.2mm layer height and 5% infill.
CR123A
CR2032
LR1130/AG26 (Thinner but similar to CR2032)
LR44/357/76
Tiny Batteries for watches/hearing aids/etc. - AG5, LR626/621, and LR516/521/526
Please comment if there is a battery not listed in these models and I can happily create more for whichever you may need. Many of these also go by a ton of different names so double check the battery you need doesn't already fit in one of the types above.
The author marked this model as their own original creation.
