Simple, neat and fits absolutely perfectly. Possible improvements include a slightly deeper version and countersunk holes. Also, a little more space between the board and screw holes (i.e. a slightly longer housing overall) would make it easier to locat the bottom screw into the backing surface when a large enough hole for the 4 pin dupont connector has been made.

Printed smaller at about 56mm tall. my 15YO son painted it and made a great job. I had to sand the lid a bit but that was my mistake in making it a bit too big when scaling down. Recommended.
