Prusa Mini/Mini+ Acrylic Enclosure Box Case Cover Kit

Regular price $225.00 Sale

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.  This is the second version of this enclosure, recently updated to accommodate both the plain MINI and the Prusa MINI base.

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, quality acrylic

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 Prusa Mini (without a base) 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.

 

Mini Base Support

We've got 4 Prusa MINIs running 24/7 at 3D Upfitters, and the only thing keeping them from being a perfect print farm machine was the side loading filament. Thankfully Prusa designed a new base with filament spool storage underneath, which was a big improvement. Still, it took four iterations of different changes to the enclosure before I was happy with it.

It's not just a matter of making the enclosure taller to accommodate the base. It has to support both the Prusa with and without the base, which still making it easier to slide the filament spools underneath.

I ended up lowering the front door scoop was to make it easier to insert the filament and making the entire enclosure a little larger to accommodate the wires that can stick out at odd angles. Those customers who don't care for the base can still feed the filament through the side door.

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.

Acrylic Thickness

 Model Description
All 3mm The entry-level model has all 3mm acrylic and is a great option for a hobbyist or someone new to 3D printing. 
6mm Front, 3mm Sides The most popular model has a 6mm front and 3mm sides.  This configuration works great for customers who expect more heavy use such as libraries or schools.
6mm Front and Top, 3mm Sides If you want to store items 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 with 3.5Kg filament rolls.
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.
