About this 3D model
This fits Evike's PEQ 1300mAh battery. I bought it here: https://www.amazon.com/gp/product/B0746VB8VP/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1. The PEQ box I got for it didn't fit, so I decided to make my own instead. I printed it out of polycarbonate, which is flexible enough to put the cover on and off, but I'm not sure about PLA.
