Prusa XL Enclosure Acrylic Case Box Tent Kit

Prusa XL Enclosure Acrylic Case Box Tent Kit

Regular price $309.00 Sale

Our Prusa XL enclosure is waiting on getting an actual printer to test.  We purchased on the very first day it was available, but that was in 2021.   We've been waiting a long time, but Prusa has indicated it may take until May just to ship the customers who purchased on the very first day.

Please bear with us while we get a printer in-house and then test our designs.

Advantages of a 3DUPfitters Enclosure

  • 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 improves indoor air quality (both sold separately)
  • A controlled temperature creates better quality prints

The enclosure kit works by retaining the bed's heat to bring the ambient temperature up high enough, stabilizing ABS and other filaments that expand when they cool. The optional fan will draw cold air across the power supply, simultaneously heating the air and cooling the supply. The heated air circulates within the enclosure, providing a steading temperature. The expelled 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)

3D Print Your Own Connectors. Or Not.

A lot of customers prefer to print their own connector pieces themselves. We get it: you've got a great 3D printer, and it is itching to print things. No problem! The kit includes the STLs for all 3D printed parts like corner connectors, knobs, vents, etc. Typically it takes about 48 hours to print everything you'll need with a .4mm nozzle and .2mm layer height.

On the other hand, if you purchase the optional connector kit, all parts are 3D printed in the best quality American-made ABS.  It not only will withstand the heat year after year, but it's also one of the most rigid plastics to add that will make the enclosure sturdier. We proudly use the best ABS filament you can buy from Atomic Filament in Indiana. 


If you still want to print your own parts, just remember that temperatures inside an enclosure will melt PLA, so you will get the best results with printing parts in a high-quality ABS, ASA, or Nylon. The catch-22 is you need an enclosure to print ABS! If you don't already have an enclosure, you can make do with PETG. Just keep in mind that PETG is more flexible and will make the entire enclosure less rigid than if you had used ABS.

Pro Quality American Made Acrylic

The panels are made in a factory in Ohio and cut on an American-built industrial laser, and then flat-packed for your assembly. All you need for assembly is just a hex wrench and a small Philips head screwdriver. (not included.)

Temperature Range

Internal temperatures vary depending on the ambient room temperature outside the enclosure as well as where you measure the temperature.  We use these enclosures to print both PLA and ABS daily, so rest assured the temperatures are "safe" to use.

For obvious reasons, we recommend always printing PLA with the fan on, and printing ABS with the fan off.

Acrylic Thickness

 Model Description
All 3mm The entry-level model has all 3mm acrylic and is a great option for the hobbyist on a budget. 
6mm Front, 3mm Sides The most popular model has a 6mm front and 3mm sides.  The thicker front is a big improvement for the door. 
6mm Front and Top, 3mm Sides If you want to use 3Kg+ spools on top of the enclosure then the 6mm top upgrade is a must.  This is the configuration we use in our print farm and it's also popular with libraries and schools that need a sturdier enclosure at a good price.
All 6mm If you want to gain a couple of degrees of heat retention or intend to move your enclosure around a lot the 6mm all-around is the best you can buy.  


Prusa MK2 Support

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.  The latest solution is a really cool dual-material and anti-vibration design from one of our customers.
