Page 3: Before You Start
You Really Do Want to Read the Directions Hey, we get it. You just got your new enclosure kit and want to start using it as fast as possible. How hard can assembling a few plastic panels possibly be? It’s not really that hard, assuming you’re following the directions, but try to use brute force and you’ll end up working through your vocabulary of swear words. - Page 4 Don’t Panic If You See This! If you can’t see through the plastic, please don’t panic! What you’re seeing is just the plastic or paper protective covering. You, dear customer, are way too smart to think the plastic is flawed and then call and email us repeatedly, leaving increasingly irate messages.

- Page 6 Identify Panels Before assembling the kit, lay out all the panels and identify which panel corresponds to the front, left, right, back, and top. Although the panels are labeled, it’s easy to get them mixed up once the covering is removed, and rarely a panel can be mislabeled. This chart will help you keep them straight.

The STLs for the 3D printed details are automatically emailed when you purchase, so check your spam filter and then contact support if you can’t find them. Please read the Blog article Printing Tips for 3D Upfitters Parts for detailed printing tips.
- Page 9 The first and most important rule of caring for your enclosure is to: NEVER USE AMMONIA BASED CLEANER! We can’t stress this enough. Certain chemicals will cause the acrylic to crack, first at the ends and then throughout the panels, and will make the acrylic hazy. The second rule is: NEVER USE MICROFIBER CLOTHS! These will create more and more scratches in your acrylic.
- Page 10 Assemble Panels 1. The Front Door Each corner of the enclosure will be held together by the connectors pictured below. There are only two versions, L and R, which can be identified by the letters stamped on the inside. The diagonally opposite connectors are identical, i.e., Bottom Right is the same as Top Left.
- Page 11 View from Outside the Front The front door is designed so that the latch is on the left. Attach the corner connectors on the inside of the door frame using the provided cap head 12mm screws. The top of the connector should be flush with the acrylic top.
- Page 12 Now that the latches are mounted, it is time to connect the strike plates. Each plate comes with a squishy adhesive covering the exact size of the plate. Carefully attach the adhesive side to the acrylic at the location of each latch. Then, adjust the width of the metal strike plate so that it is held on by the pressure of the two sides of the plate.

- Page 14 The U-shaped hole is for the cable grommet and holder. This will allow you to remove the enclosure without unplugging the cables! 3. Assemble Back The view to the right is the back panel of the MMU2 Prusa enclosure when viewed from behind.
- Page 15 Use the long screws included in the fan packet to attach the fan. The length of the screws may change depending on the depth of this particular shipment of fans. The U-shaped hole is for the cable grommet and holder. This will allow you to remove the enclosure without unplugging the cables! 4.
- Page 16 5. Attach Top This enclosure has an optional dry box attachment on top, shown at right. If you do not have a dry box option, skip ahead to the cross beam installation. If you have a dry box top, there is an additional M4 20mm hex cap screw to attach to each top corner connectors circled in red below.
- Page 17 Cross Beam Now is an excellent time to install the cross beam that adds support to the top if you want to put the spool holder on top. (See beam circled in red in the illustration to the right.) It should just slide into the slots as shown before you attach the top.
- Page 18 Should you want to print these parts yourself, the STL files are available directly from Prusa, or you can download them from the 3DUPfitters MMU2 product page. There are three separate spool holder support pieces to print in file prusa_mmu_enclosure_9.3mf: These are attached to the top using 16mm M4 screws on the holes near the front of the enclosure top.
- Page 19 The final piece to print is in file prusa_mmu_enclosure_4.3mf: Copyright 2023 3DUPfitters LLC...
- Page 20 These two pieces allow the filament buffer to be attached to the top. Once the top is assembled, you can connect the PTFE tubes for the multi-material unit to the filament buffer. We can’t provide a complete list of instructions since the buffer is a Prusa product with a multi-material unit.

- Page 22 Connecting the Top to the Corners If you have the dry box addition, the top will fit around the M4 20mm screws you previously attached. (Circled in red, to the right.) If you did not purchase the dry box, you can leave this center hole unfilled or use an M4 12mm hex cap screw from the outside.
- Page 23 6. Sealing Gaps Once the enclosure is completely put together, it is time to make sure that each panel is held tightly to each adjoining panel. The connectors are designed with a small amount of play that allows you to make minor adjustments for the perfect fit. 1.
- Page 24 7. Plugging Things In There are a couple of things to the plugin: the Prusa itself and the fan. The old-style silver Power Supply Unit plugs in through the vent. Instead, if you are using the newer black power supply, the power cable goes through the grommet in the back.
- Page 25 9. Optional BlazeCut The BlazeCut fire extinguisher mounts to the top of the enclosure using the provided U-shaped brackets as shown. It fits in and around the MMU2 spool holders and detangled. 10. Optional Dry Box Top The dry box is a top that fits over the filament spools and, when combined with desiccant (not included), prevents the filament from absorbing water.
- Page 26 If the top seems to overhang the front or back incorrectly, try replacing the front and back panels if they are of different thicknesses. The dry box construction is slightly different in that it uses special corner connectors on the bottom corners. These are distinguished by the words “dry box” on the side below.
- Page 27 The special dry box connectors are used on the bottom corners as shown circled in red: Copyright 2023 3DUPfitters LLC...
- Page 28 Once the dry box is assembled, it fits over the top of the enclosure using the screws installed in Step 5 as a guide to hold it in place. The back of the dry box has a unique grommet holder for the PTFE tubes that run from the detangled into the MMU2 unit through the back of the...
- Page 29 11. Managing Enclosure Temperatures There's not much to a 3D printer enclosure. Although ours look fancy, functionally, they're not much different from putting a cardboard box over the printers since both designs are passively heated by the beds. How complicated can they be? This section will explain how they work and how to manage the temperatures to get quality prints while protecting your lungs.
- Page 30 Passively heated enclosures depend entirely on the room temperature as a starting point. If you're trying to print ABS in an unheated garage in the winter, the temperature inside the enclosure will never get hot enough. The bed heater has only enough energy to increase temps from the baseline.
- Page 31 If you'd like to lower the temperature further, you can always buy a more powerful fan, but the easiest thing to do is crack the front door a little to increase airflow. But won't that let out all of the volatile organic compounds coming off the hot end? The key is the negative pressure combined with the particles' minimal and light.

Page 32: Tips And Tricks
Let Us Help If you're looking to achieve a particular temperature with your enclosure, let us know, and we'll give some advice on how to manage, but it's not that hard: Lower Temperature = More Cold Air Higher Temperature = Less Cold Air Pro Tip: measure your current temperatures before attempting to make any changes. - Page 33 13. DIY Tool Holder Our favorite customization is to add magnetic tool holders to the side. One end can be attached via the same hole as the corner connectors, but the other end will require drilling a single hole. You can find magnetic strips like this all over Amazon or your local hardware store.
