Button Cell Holder Kechain

My car keys use these 3V button cells and I designed a little keychain holder that I can attach to my keys so I always have a set of spare batteries.

Holds 2 x 3V button cells (⌀20mm x 2,5mm each)

Print in PLA, the two halves will snap together firmly once cooled down. To open it again, rotate the halves so that you can use the little tabs to lever it open. Should be pretty self explanatory.

Feel free to use this for whatever you want or even sell them, no attribution needed :)
