Okay it is done, 2mm wall thickness, 0.2mm to 0.5mm layer height should be fine. You can print just side1 and side2, but then you’ll need magnets to hold the 2 halves together, or print the base, and just shove the 2 halves in, no magnets required. Designed to work with 4mm thick, 4mm diameter round button magnets. Uses passive vertical cooling, or you can throw in a 3705 fan for good measure. Version 1 so there could be bugs!
