⬢From the rear side of the PSU holder, push the zip tie through the perforation on the holder.

⬢Tighten the zip tie around the PSU cable bundle.

⬢Carefully put the printer with the PSU aside for now. We will come back to it in a while.

⬢Ensure the PSU-locks are still turned at the same position:

⬢Place the PSU on the heatbed protected with the cloth.

⬢Turn it with the PSU-handle facing upwards.

⬢The PSU cable bundle must guide to the left.

⬢To get the printer into the enclosure, insert its left side first.

⬢Place the printer at an angle (as shown in the picture) in the enclosure behind the anti-slip dampers.

⬢Insert the PSU through the hole at the bottom of the back panel. Start by pushing through the part with the PSU-retainer (the part with the magnets).

⬢Insert five M3n nuts into the Filament-guide-a.

⬢Attach the Filament-guide-b on the Filament-guide-a part and join them together by three M3x8 screws. Do not tighten the screws completely, a few turns are enough for now.

⬢Slide the PTFE tube all the way into the hole in the filament guide. From the opposite side, check if the PTFE tube is completely inserted to the end. If not, slide the PTFE a little more. See the direction of the PTFE tube.

⬢Tighten all screws on the filament guide assembly. Do not overtighten the screws! Check that the filament passes easily through the PTFE!

⬢Align the holes in the filament guide and holes in the front-right top corner of the frame. See the orientation of the filament guide.

⬢Insert two M3n nuts into the Thermometer-bracket.

⬢Pull out the plastic tab from the temperature sensor.

⬢Insert the temperature sensor in the Thermometer-bracket. Push on it by your thumbs until you feel a slight "click". Avoid pressing on the screen, you can damage it.

⬢From the inside, mount the thermometer to the top left corner. Secure it with two M3x8 screws.

⬢Door panel (2x)

⬢Door-magnet-a (2x)

⬢Push the magnet all the way into the pocket.

⬢Insert two M3n nuts into each Door-magnet (A and B) part.

⬢There are protective foils on both sides of the panel. Peel off both foils.

⬢Place the edge of the door panel on the door trim. Both sides of the panel are symmetrical. It doesn't matter which side you put it on the door trim. It is important that the circular hole is placed on the door trim.

⬢Align the edges of the door panel with both ends of the door trim.

⬢Proceed the same with the second door panel.

In the next step, we will need door-magnet-a and door-magnet-b. These parts are not the same! Both parts are marked with the letter "A" and "B" and have a different shape.

⬢Insert the door-magnet-a under the left side of the door trim and the door panel.

⬢Place the Door-handle under the door assembly and align the holes with the screws.

⬢Join the parts together by tightening the M3x12 screws.

⬢Proceed the same with the second door assembly.

⬢Take one of the door assemblies and place it on the open hinges on the right side of the enclosure. Make sure the handle is on the outside of the panel.

⬢Secure the door assembly by tightening two M3x8 screws in each hinge.

⬢Take the second door assembly and place it on the open hinges on the left side of the enclosure. Make sure the handle is on the outside of the panel.

⬢Secure the door assembly by tightening two M3x8 screws in each hinge.

⬢Insert the Top-plug-edge to the cutout in the front of the top panel.

⬢The top surface of the printed part must be flushed with the top surface of the profile.

⬢Secure it with the nylon rivet.

⬢Install the second Top-plug-edge to the same cutout on the rear side of the top panel. Secure it with the nylon rivet.

⬢Insert the Top-plug-center in the rectangular cutout in the center of the top panel. Secure it with two nylon rivets.

⬢Completely insert two M3n nuts into the holes in the Spool-holder-r.

⬢From the inside, attach the Spool-holder-r to the corner on the right side of the enclosure. Secure it with two M3x12 screws. See the orientation of the Spool-holder-r.

⬢Insert the side arm into the Spool-holder-r and turn counter-clockwise to lock it.

⬢After assembly, ensure there is sufficient space between the inside wall of the enclosure and the Nextruder when it is in the top-right position. When printing at the full height of the printer, the Nextruder may come into contact with the filament spool. To prevent this, place the spool on the spool holder as far to the right as possible.

⬢Prusament spools are not affected by this when positioned correctly.

⬢These instructions are the same for the Original Prusa MK4/3.9.

Some of the following steps are marked as optional. If you do not need to install the handles at this time, skip to Reward yourself!

⬢M3x12 screw (6x)

⬢Insert two M3nS nuts from the side into each Transport-handle.

⬢Insert the M3nS nut from the other side into each Transport-handle.

⬢Using the knife, CAREFULLY cut off all supports of each handle cutout on the side panels and remove it.

⬢From the inside of the enclosure, push on the nylon rivets using the pliers. And pull them out from the outside.

⬢From the inside, place the Transport-handle into the same shape cutout.

⬢Secure it with three M3x12 screws.

⬢Repeat the same procedure for the second Transport-handle.
