Prusa Mini/Mini+ Acrylic Enclosure Box Case Cover Kit

Regular price $225.00 Sale

Includes Free Spool Holder

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 under an hour.

Advantages of adding a 3DUPfitters enclosure:

  • The controlled temperature creates better quality prints
  • More flexibility to print different types of filaments
  • Optional air 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. 

Side Access

The biggest difference between this enclosure  box/case/cover 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.

This video shows how the negative pressure keeps a steady stream of air coming into the enclosure where it blows VOCs and other harmful particles out through a vent or air filter.  Then the hot end moves up so you can see how the filament isn't impeded by the enclosure.


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 nice spool holder so one is NOT included in this kit.

Kit Includes

  • Enclosure Dimensions: 19" (Deep), 17.72" (Wide), 17" (Tall), 13 lbs.  
  • Fits the Prusa Mini ONLY
  • Acrylic front panel with frame, doors, injection-molded hinges, magnetic latch, custom-designed latch mount in ABS, steel strike plates, and matching screws.
  • Acrylic spool holder
  • Acrylic sides and top with access ports for cables and filament. There is no bottom. The enclosure is designed to sit on a flat surface that acts as a bottom.
  • 60x60mm 12.6 CFM USB-powered fan.  3D print a cover if you don't wish to vent.  (USB power supply not included.)
  • Hundreds of screws, nuts, bolts, all connecting plastic pieces, and miscellaneous parts. 

Acrylic Thickness

The base enclosure has a 6mm front and 3mm sides.  This configuration has been in production for years and works fine with hobby use and 1Kg filament spools.

If you want to use 3Kg+ spools on top of the enclosure then the 6mm top upgrade is a good idea.  This is the configuration we use in our print farm and it works great.

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.  Note that if you choose that option you don't also have to purchase the 6mm top upgrade.
