3D Printer Not Included

Note:  This enclosure is specifically for the stock Prusa MK3/S with MMU2 installed.  If you want to handle the stock Prusa MK3/S that is a different enclosure.

Have you modified your printer?  Let us know before buying!

The Prusa MKS line has the capabilities, fit, finish, and attention to detail of a much more expensive printer. In a market awash with inexpensive printers full of crappy parts that wear out quickly, everything about the Prusa i3 is quality. Its hot end can print anything, there's a best-in-market removable bed, and the slicer is tuned to make the most of the printer.

The only thing the Prusa lacks is an enclosure to make full use of its capabilities. Our Prusa enclosure retains the offensive odors and air contaminates from melting plastics and creates better-looking prints to boot. This product is a professional-grade, cool-looking enclosure you can assemble in about an hour and works with a stock Prusa MK3: no modifications needed. 

Advantages of adding a 3DUPfitters enclosure:

  • A controlled temperature creates better quality prints
  • Provides outside air to the power supply with no modifications to the printer
  • More flexibility to print different types of filaments, including ABS
  • Optional fume filter or vent to the outside (both sold separately)
  • Thick 6mm acrylic doors and 3mm sides

The enclosure works by retaining the bed's heat to bring the ambient temperature up high enough, stabilizing ABS and other filaments that expand when they cool. The optional fan will draw cold air across the power supply, simultaneously heating the air and cooling the supply. The heated air circulates within the enclosure, providing a steading temperature. The expelled air can be vented into the room, sent through an optional air filter (not included), or vented to the outside via a hose. (not included)

Multimaterial Unit (MMU2S) Support

The MMU2S version of the enclosure fits your Prusa if it has an MMU2 installed.  If you haven't received your MMU2 yet, the enclosure works just fine without it as well. We made this version much wider and deeper so that you can store all five spool holders and the filament detangler on top. To make sure the top can safely accommodate all five filament spools it's been doubled in thickness to 6mm.  

Note that since the spool holder and detangler holder are from Prusa we don't print them for you, but we did collect the required files for you to make it easier.


How it's Built

All of the plastic parts are 3D printed in ABS to withstand the heat from the enclosure. The panels are cut on a US-made industrial laser and then flat packed for your assembly.   All you need for assembly is just a hex wrench and a small Phillips head screwdriver.  (not included.)

What's Included
