Here is a battery holder I designed to keep track of my rechargeable AA batteries. Both battery terminals can be accessed without removing the battery. Batteries can be put in upside down to keep track of charged and discharged batteries. Case holds 9 AA batteries and can be stacked without the battery terminals touching. Batteries fit nicely without sticking.

The 2 STL files are mostly similar with the exception of some small chamfers to reduce sharp edges. Designed for SLA printing, I am unsure if this will print without modifications for FDM printing. I added the several pockets to reduce the amount of resin consumed. Prints well using Creality HALOT-MAGE Pro Dynax++ Mode in about 2.5 hours. Use a 50% mix of your favorite hard resin with "Siraya-Tech Tenacious Flex Black". I used "One-Peng White Model Resin" in the pictured print for my hard resin.

Unfortunately I cannot upload the print file with supports that is ready to print for SLA printing, it seams only FDM files (gcode) is only allowed, hopefully Creality will allow cxdlpv4 files for SLA. I will keep checking and upload the ready to print file when it is allowed.

Commercial Use Allowed: so if you become rich off this design please send me some $$$ to keep me interested in making more models for commercial use.
