This is a simple box to put a communication board of the JK-BMS inverter BMS (model JK-PB2A16S20P) that I use in my DIY solar energy storage system. Letters on the box could be filled by the nail polish or sealant to make letters stand out.

Included Fusion 360 files as well if it will help someone to create their own enclosure faster.

Top cover could be printed on smooth PEI or Engineering Plate facing down, then engraving of letters will look better could be filled by acrylic paint of contrasting colour.

In version_2 of the enclosure a cut out was added for the ON/OFF button, if you wish to place it on the box and not on the battery enclosure/shelf.

Use M3*6 screws to attach the board and top cover.
