USB Voltage Regulator Case

Here's my first attempt to design and 3D print a small case for an electronics device. The device is an inexpensive USB input buck-boost voltage regulator available on Amazon that I plan to use for a telescope Ra drive (small DC motor controller).

Device:
ALAMSCN DC-DC USB Buck Adjustable Boost Converter Step UP/Down Power Supply Module 3.5V-12V to 1.2V-24V (Pack of 2)

I printed the case using Prusament PLA with the default MK3S+ settings except I used perimeter setting = 4 to ensure the M2 heat-set brass inserts didn't melt the sides. The four screws are M2 x 12mm L. I also used some double sided foam tape (approx. 1.5mm thick) on the inside so the top half would lightly 'squeeze' the PCB against the case bottom half.

Lessons learned (for next time)... the 'engraved' letters need to a bit larger to print properly. Could also decrease my tolerances (allowed 'gaps') for a closer
