After all the tightening and Allen key usage by building the MK3S, I didn't have enough. So I made a screw that you can tighten forever! I made this screw head for an LCD knob based on most of the screws in the MK3S, the M3 rounded head screws. In addition I made a cute version of the Allen key, with a rounded side. It fits perfectly and works as it should, if I do say so myself. I think you should try it out! It does not need supports nor brims. Although I might suggest using a smooth sheet.
