This is a box designed to fit a particular design of lithium (and Lead acid) capacity meter available on Aliexpress and eBay (see image) for example: https://www.aliexpress.com/item/LCD-Lead-Acid-Lithium-Battery-Capacity-Indicator-Digital-Voltmeter-GY-6-12V-24V-36V-48V-6/32888219678.html.

The back of the box clips to the front to provide a nice simple box. There's a lip on the front so you can panel mount it if you like. There's also two screw holes on the back so you can screw it to something also.

I printed it at 0.2 mm later height which looks fine.
