Prusa MK2/MK3/MK3S+ Acrylic Enclosure Kit

Regular price $275.00 Sale

This enclosure box is specifically for the stock Prusa  MK2/MK3/S.  If you want to handle the MMU2 multi-material attachment that's a different enclosure.

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

The Prusa i3 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.

Includes Free Spool Holder

The only thing the Prusa lacks is an enclosure box or case 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 i3: no modifications needed. 

Advantages of adding a 3DUPfitters enclosure:

  • 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 improves indoor air quality (both sold separately)
  • A controlled temperature creates better quality prints
  • 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)

Prusa MK2 Support

Note that because of the close tolerance around the power supply, the height of the printer must be stock for the MK3 with its rubber feet. The MK2 will also fit, but getting it to be the correct height will involve the use of one of the many feet available on Thingiverse.  The latest solution is a really cool dual-material and anti-vibration design from one of our customers.

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

  • Regular Prusa Enclosure: 22.5" (Deep), 17.72" (Wide), 16" (Tall), 13 lbs.
