This was built to be a simple, no-frills enclosure for the FluidNC 4x CNC control board that provided active cooling for the drive circuity. Designed to be a tight fit around the PCB, it exposes all connections and ports through cutouts in the sidewalls. Additionally, there is an antenna mount on the side for the ESP32's external antenna. In my personal experience, the active cooling provided by this case has made a significant improvement in allowing the motor drivers to maintain a reasonable temperature and avoid thermal shutdown.
The enclosure is designed around 2x 40mm PC fans. I would personally suggest 5v fans so that you may utilize the headers exposed on the 4x board to directly power them, I personal am using these and have had no issues: https://link.amazon/B0icz9T4G
The 4x control board is intended to be mounted with M3 bolts to the enclosure, and the design is such that an M3 nut should be recessed into the backside to bolt into. The cover can also be attached with M3 bolts if needed, however I have found the friction fit to be plenty. The cover is designed such that the M3 bolts should thread directly into the plastic and not need a nut! If you need any bolts, I'd certainly suggest one of these general kits as they are incredibly convenient to have around: https://link.amazon/B0gknG8go

My personal suggestion would be to print this in PETG with at least 2 perimeters and 15% infill, however these are not rigid requirements and nearly any filament and settings should be fine.
