Update: New version added, see updated text below.

The injection molded xLCD case that comes with the MK4S looks really great. Unfortunately, if you want to mount it on the outside of the enclosure, you have to remove the back plate to be able to mount the original Prusa enclosure adapters, leaving the circuit board completely exposed and unprotected.

While looking for a solution, I came across this design by @Schorsch3000 and adapted it a little for my needs. The following versions are available to now:

Initial version V1:

  • As I didn't have any heat set inserts, I adapted the original design to use M3 nuts, which are supplied in sufficient quantity with the printer and housing. The fit of the nuts is quite tight so they can't fall out. I recommend pressing them in with a screw clamp or a small vice.
  • I have adapted the design so that the user-facing side of the adapter can be laid flat on the print bed. This gives a very nice look, especially when using a textured printing plate.
  • I slightly increased the distance between the bottom edge of the xLCD housing and the base.

Reinforced version V2:

  • Version V1 had the problem that the adapter bent slightly backwards when the rotary knob was pressed. The new version V2 is now significantly reinforced to prevent this. 
  • Due to the increased thickness of the adapter, I had to recess the nuts slightly so that the Prusa thumbscrews would still fit. To keep the look as clean as possible, the recessed nuts can now be hidden with blind plugs.
  • I have increased the distance between the bottom edge of the xLCD housing and the base a bit further compared to V1.

Images show prints from an MK4S in Galaxy Black PETG. The adapters have been printed with  0.2mm structural with 15% infill, 4 perimeters and organic supports. Blind plugs have been printed using 0.1 mm fast detail standard settings.
