3D Printer Not Included

The Prusa Mini was released in November of 2019 and was an immediate hit, with waiting times of months to get one. We were lucky enough to buy the first day and so only had to wait two months.  The Mini itself is a wonder of engineering designed to reduce costs and increase reliability.  The cantilevered hot end gets all of the attention, but the redesigned hot end with its custom integrated heat sink is both simpler and more effective than on its bigger MKS cousin.

The only thing the Prusa Mini lacks is an enclosure to make full use of its capabilities, as well as retain the smells and air contaminates from melting plastics.  This product is a professional-grade, cool-looking enclosure you can assemble in about an hour.

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 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.  

Side Access

The biggest difference between this enclosure and the Prusa MKS enclosure is the addition of a side door.  The Mini is designed to feed filament through the Bowden tube on the side, and the power switch and USB port are all there.  To make access easy a side door is right where you need it.  There's a gap on the edge of the door so that as the gantry moves up and down the filament has a slot for unrestricted access.


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.)

Note: The Mini comes with a spool holder so one is NOT included in this kit.
