Aether Mini UPS case

I needed a case for my mini ups PCB from AETHER so I designed it.The case is designed for the 5V PCB model with USB-C connector but it works also with 12V one with other USB connectors. If you want to change the text 5V on the side there is the original Fusion file to modify it. The cover fits perfectly into the case but according to your printer and calibration could not close very well.The holes in the cover are needed as 18650 Li-Ion battery heats. Feel free to comment and suggest any improvement to the design
