Prusa MK3S+ MMU2+ Acrylic Enclosure Box Case Cover Kit

Regular price $275.00 Sale

Note:  This enclosure case is specifically for the stock Prusa MK3/MK3S/MK3S+ with MMU2/MMU2+ installed.  If you want to handle the stock Prusa MK3/S that is a different enclosure.  (Although it will work fine with your printer with no MMU2 installed.)

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 box/case/cover 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:

  • Optional fume filter or vent to the outside improves indoor air quality (both sold separately)
  • 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

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 is designed for your Prusa if it has an MMU2 installed, but also works if your Prusa does NOT have an MMU2 installed.  Just feed the filament through the slit in the top using a regular spool holder.  That way you can use the enclosure until the MMU2 arrives.

We made this version of the enclosure 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 MMU2 spool holders 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.

 

3D Print Your Own Connector Pieces.  Or Not.

A lot of customers prefer to print their own connector pieces themselves. We get it: you've got a great 3D printer, and it is itching to print things. No problem! The kit includes the STLs for all 3D printed parts. Typically it takes about 48 hours to print everything you'll need with a .4mm nozzle and .2mm layer height.

On the other hand, if you purchase the optional connector kit, all parts are 3D printed in the best quality American-made ABS.  It not only will withstand the heat year after year, but it's also one of the most rigid plastics to add that will make the enclosure sturdier. We proudly use the best ABS filament you can buy from Atomic Filament in Indiana. Note that purchasing the pre-printed parts kit still does not include the spool holders from Prusa, although we do distribute their STLs.

DON'T USE PLA!

The catch-22 is you need an enclosure to print ABS! If you don't already have an enclosure, you can make do with PETG. Just keep in mind that PETG is more flexible and will make the entire enclosure a little less rigid than if you had used ABS. If you still want to print your own parts, just remember that temperatures inside an enclosure will melt PLA, so you will get the best results with printing parts in a high-quality ABS.

Pro Quality American Made Acrylic

The panels are made in a factory in Ohio and cut on an American-built industrial laser, and then flat-packed for your assembly. All you need for assembly is just a hex wrench and a small Philips head screwdriver. (not included.)

 

Acrylic Thickness

 Model Description
6mm Front and Top, 3mm Sides The most popular model has a 6mm front, 6mm top, and 3mm sides.  This configuration works great for customers who expect more heavy use such as libraries or schools.
All 6mm If you want to gain a couple of degrees of heat retention or intend to move your enclosure around a lot you can't go wrong with the 6mm all-around option.
