Prusa Box Enclosure - HEPA & Carbon filter cover for Noctua industrial fan

This cover is based on a newer version of the HEPA filter: https://help.printer-box.com/home/download/#elf_l1_UHJ1c2EtYm94L01vZHMvMDA1X0hFUEEtQ2FyYm9uIF9maWx0ZXI (the one on Printables is the old version)

The height of the cover and the spacing of the holes are modified to fit Noctua industrialPPC NF-F12 3000 PWM with the rubber bumpers.

Check the 3MF or the gcode for printing directions, the grill should be facing the printbed, it can be printed without supports this way. 

I've also made a special version with some slide-on cable guides.

The cable guides are a tight fit by purpose, you can insert the cable the following way:
- pinch the cable to have a flat cable instead of a round one
- push the flattened cable in

- twist the cable 90 degrees

- slide the cable guides in the rails/holders on the fan cover

Why this 2 part setup: this is needed to be able to print everything without supports.
