Prusa Mini/Mini+ Acrylic Enclosure Box Case Cover Kit
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)
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.
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 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.
The entry-level 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 put items that weight more than 1Kg on top of the enclosure then the 6mm top upgrade is a good idea.
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.
