Battery tray for Heltec WiFi LoRa 32 (V2) minimal case

This is a battery case for this thing https://www.thingiverse.com/thing:3783207. You have to print this 2 parts first. If you want to use it with a small 1000mAh LiPo you can easiliy print my battery case and put it behind this thing.

I used 3 M2.5 nuts and screws for securing all 3 parts together. Therefore I drilled the originally holes a little bit wider.
