This is enclosure is specifically for those who have purchased the MMU2 multi-material attachment, but still works with the regular MK3/S if your MMU2 hasn't arrived yet. It makes use of the layout Prusa recommends in its DIY MMU2 enclosure kit, with the spool holders and filament detangler on the bottom.
While the DIY version looks like a fun build, for those of us who don't have the time or simply prefer the look of all-acrylic, this product is a professional-grade, cool-looking enclosure kit you can assemble in about an hour.
Advantages of adding a 3DUPfitters enclosure:
The bulky spool holders and filament detangler box are stored right on top.
Optional fume filter or vent protects your indoor air quality.
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
Thick 6mm acrylic door and top and 3mm sides
The enclosure works by retaining the heat from the bed to bring the ambient temperature up high enough, stabilizing ABS and other filaments that expand when they cool. The optional fan will draw cool air across the power supply, simultaneously heating the air and cooling the supply. The heated air circulates within the enclosure, providing a steading temperature; from there the 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)
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.
Multimaterial Unit (MMU2S) Support
This enclosure is specifically designed for when you have an MMU2 or MMU2S installed now or plan to get one in the future. The enclosure was made larger so that the Prusa-designed spool holders and filament detangler (comes with the MMU2) can fit on top of the enclosure.
How it's Built
All of the enclosure 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.)
