This is a slim case that requires no screws for assembly. In fact, the clips on my printed version were so tight that I believe they are 'forever'.

Added some vents for heat, and I routed my antenna cable between the RJ-45 and USB ports. Wouldn't be difficult to disconnect the antenna and push it through a vent if desired.

Printing requires no supports, just place the flat side of each half on the print bed. To assemble, carefully guide the 4 clips to their slots.

Update 08-23-2023 - added a version of the case top with a 16x16mm heatsink opening
