I designed this nozzle holder to fit in place of the LCD screen on the Prusa Mk3 printer, for folks who (like me) have their LCD screen mounted outside of an enclosure.
When the LCD screen is mounted outside of an enclosure it leaves the front of the printer unused (and fairly ugly), so I decided to make use of it by designing this nozzle holder, which can take up to 10 nozzles, and also hold the E3D nozzle wrench/spanner.
The version I printed includes lettering for identifying multiple 0.25, 0.4 and 0.6 nozzles, but I will also provide a version without numbers so that it can be used for different nozzle size combinations.
The holders for the nozzles are all threaded, so that the nozzles can be screwed in, and won't fall out.
The holder can be printed at standard 0.2mm layer height, with a 0.4mm nozzle, and the threads should work just fine (but the lettering might look better with a finer nozzle).
It attaches using the existing screws and holes for the LCD, and uses the same four captive square nuts from the LCD screen. (or you can use spares if you need them for your LCD enclosure mounting solution)
No supports should be needed for this part (I printed it ok without supports).
Just in-case the parts aren't automatically orientated correctly by your slicer, make sure to print face-down (nozzle holes towards the bed)
