Tools that are not included but can make assembly easier, especially when installing add-ons.
⬢Additional tools:
⬢Side cutters for cutting zip ties and removing the nylon rivets
⬢We have designed enhancements that are not shipped by default in the kit, but you can print them out and add them to the enclosure during assembly. Fasteners are already included in the kit.
Print out the parts before you start assembly.
⬢To see the full list of the parts, please visit our collection at Printables.com.
⬢Grasp the Spool-holder-r and turn clockwise to unlock it and remove it from the MINI Enclosure.
⬢Pull the power cord handle towards you to release and disconnect the power cord from the back of the printer.
If the space is difficult to access, move the printer closer to the front, avoiding scratches on the panels.
⬢If necessary, disconnect an ethernet cable.
⬢Disconnect the USB extension cable from the right side of the printer.
⬢From the front side of the MINI Enclosure:
⬢Move the heatbed towards you.
⬢Carefully take the printer.
⬢Carefully pull the printer out of the MINI Enclosure with the base facing backwards. Be EXTRA CAREFUL when doing this:
Ensure the X-end and aluminum Z-axis profile pass through the right and left cutouts of the front opening. Use EXTRA CAUTION to avoid damaging the printer or enclosure.
⬢Hold the heatbed with your left hand to prevent it from sliding down and getting damaged on the bottom plate.
⬢During pulling out the printer, look carefully at all sides of the printer to ensure that nothing is in the way (e.g., cables, motors, etc.).
Ensure that no parts of the printer touch the side panels to avoid scratches.
⬢Put the printer aside.
⬢For the following steps, please prepare:
⬢Damper (3x)
⬢Thumb nut M3 (3x)
⬢M3x8 screw (3x)
⬢M4x16b countersunk screw (2x)
⬢Blower o-ring (1x)
⬢Filtration pack (1x)
⬢Push out the filter from the filtration pack and divide the pack into these individual parts:
⬢High Pressure Blower (1x)
⬢HEPA filter (1x)
⬢Filter-Bracket (1x)
⬢Place the Filter-Bracket like in the picture and push the Allen key through the hole as you can see.
⬢Attach the M3x8 screw on the tip of the Allen key.
⬢Using the Allen key, push the screw all the way through the front hole of the bracket. The screw must protrude partially.
⬢Tighten the damper on the screw.
⬢Repeat the same procedure to install the second damper.
⬢Using the Allen key, push the M3x8 screw through the protrusion on the other side of the Filter-Bracket.
Leave the marked hole empty.
⬢Tighten the damper on the screw.
⬢Place the Blower o-ring into the Filter-Bracket.
⬢Insert the High Pressure Blower into the Filter-Bracket so that the blower of the fan faces the hexagonal holes in the printed part.
⬢Join both parts together with two M4x16b countersunk screws.
⬢Tear open the filter bag and remove the HEPA filter.
Handle the filter with caution. If the HEPA surface (the white pleated surface) is damaged, the filter will lose its efficiency. Protect your hands when you take off the used filter and put it in a plastic bag. A saturated filter is not recyclable.
⬢Orient the filtration assembly according to the picture. Make sure that two brackets are facing you and the cable is pointing to the left.
Make sure that the HEPA filter is already removed from the bag.
⬢From the left, push the HEPA filter all the way into the Filter-Bracket. Mind the orientation of the filter.
⬢From the inside, remove the nylon rivet on the left upper corner.
Hint: use a Side cutters from inside the enclosure to push the nylon rivet out
⬢From the inside, attach the filtration to the rear side of the Enclosure "frame" so that all three screws go through the holes.
⬢Secure all three damper screws by tightening three thumb nuts.
⬢For the following steps, please prepare:
⬢Zip tie (5x)
⬢Guide the zip tie thought the perforation in the top panel near the filtration.
⬢Using this zip tie, secure the filtration cable. Do not overtighten the zip tie, as it may cause fatal damage to the cable.
⬢In the same way, secure the cable to the four perforations in the left rear profile. Do not overtighten the zip ties, as it may cause fatal damage to the cable.
⬢Leave the rest of the cable free for now.
From October 2024 you may receive two different manufacturers of the PSU, the pictures may be different but the assembly process is the same.
⬢For the following steps, please prepare:
⬢PSU (1x)
⬢Zip tie (7x)
⬢Slightly loosen the left screw behind the circle hole.
⬢Release and remove the right screw. Don't throw the screw away!
⬢Remove the printer PSU cable from the rear hole.
⬢Reposition the foot as shown in the picture. Keep the cable in the cable channel.
Exercise caution when handling anything inside the enclosure. There are sharp metal plates, so avoid injury.
⬢Insert the PSU cable with the ferrite core through the circular hole at the rear of the Enclosure.
The ferrite core is smaller than the hole, slowly push it through the hole.
⬢Guide the PSU cable with the connector through the front circle hole out of the Enclosure.
⬢Insert the printer PSU cable back through the rear hole.
⬢Close the foot back to its original position and align the holes in the foot and Enclosure.
Tip: You can inspect the position through the Top window panel.
⬢After aligning the hole, secure the foot by inserting back the M3x12 screw.
⬢Fully tighten the left screw.
⬢Release and remove both M3x12 screws.
⬢Reposition the foot as shown. Push the PSU cable into the cable channel.
⬢Push the PSU cable into the cable channel.
⬢Close the foot back to its original position and align the holes.
⬢Secure the foot by inserting back the M3x12 screws and tighten them firmly.
Exercise caution when handling anything inside the enclosure. There are sharp metal plates, so avoid injury.
⬢Guide the cable along the rear side of the Enclosure and secure it using three zip ties through the perforations. Do not overtighten the zip ties, you can damage the cable.
⬢Guide the PSU cable along with the FAN cable on the left side of the Enclosure and secure it with the three zip-ties. Do not overtighten the zip ties, you can damage the cables.
⬢If you have installed the Advanced Filtration System, guide the filtration cable together with the PSU cable. Secure it with one extra zip tie in the left corner. Do not overtighten the zip tie, you can damage the cables.
⬢For the following steps, please prepare:
⬢Basic Board Cover (1x)
⬢Basic board (1x)
⬢M3w serrated lock washer (2x)
⬢M3nS nut (2x)
⬢M3x12 screw (2x)
⬢Mount the M3nS nut on the M3x12 screw. Attach it in a few threads on the tip of the screw.
⬢Push the screw with the nut all the way into the same shape hole inside the Basic Board Cover.
⬢Remove the screw from the nut.
⬢Use the same procedure for both slots in the Basic Board Cover.
If you already have an LED strip panel installed, leave the LED cable in the Basic board slot labeled LED.
⬢Connect the filtration cable to the Basic Board slot labeled FAN.
⬢Place the Basic Board into the Basic Board Cover and align the holes on both parts.
⬢From the inside the Enclosure, insert two M3x12 screw through the front profile.
⬢Attach two M3w serrated lock washer on the screws.
⬢Take the Basic Board assembly and align the holes with the screws in the profile.
⬢Attach the Basic Board assembly to the screws and tighten the screws from the inside.
⬢Connect the external PSU cable to the basic board from the left side.
⬢It is recommended to make a loop with the excess cable and secure it with a zip tie. This way, the cable will not get in the way. Do not overtighten the zip ties, you can damage the cable.
These steps are only for LED strip and Advanced filtration system owners only. The smaller PSU space is for those with additional PSU. Otherwise, skip to Door hinges: parts preparation
⬢PSU holder is not included in the package, you will need to print it out from Printables.com
Before starting printing, check what type of PSU you have!
⬢XP PSU: This PSU is larger than the Delta PSU. You will need the PSU-holder-XP.
⬢Delta PSU: This PSU is smaller than the XP PSU. You will need the PSU-holder-Delta.
These steps are only for LED strip and Advanced filtration system owners only. The smaller PSU space is for those with additional Delta PSU. Otherwise, skip to
