Filter holder for Prusa Enclosure and rack server cabinets (120x120 fan). It is cheap, fast to make and simple as possible. Holder is designed for Zortrax filter set (Hepa + Carbon), but any square filters up to 27mm thick will fit. You can use it also as soldering fumes extractor.
Holes on the front are to help with screwdriver for M4 screws, I didn't want to make frame too thin.
Print it with supports, but it is enough to support it in suggested areas (see attached pictures).
I recommend to mount it with distances, you can print it, see my other desings.
