Just a basic battery holder design I did to suit my needs. Holds AAA, AA, and CR123 batteries. I printed in PETG but PLA works just fine. I would recommend turning on “detect thin walls” if you print more than 2 walls as it will affect the walls of the AA holes due to spacing. Im working on a V2 that includes a lid but havent quite decided what type of lid i want. Will post that as soon as I finish it. 

Feel free to remix, share etc. This was my first 3D design as I am pretty new to the 3D printing world. Hope you like it!
