This is a remix of the original nozzlebox with options that fit Volcano and MK8 nozzles. Like the original, it prints in place and is locked by a magnet (6x2mm!) and an M3x6 (or smaller) screw. It doesn't come with any markings so that one can just add a sheet of paper (of which I attached a paper with the exact dimensions for a print-out)
The contraption is printed at an angle so that even dirty nozzles should fit – the bottom of the contraption is ~7mm apart while the top is ~6mm.
Thank you very much @dodasch for the original. It's been a very interesting journey trying to recreate this neat design.
The Onshape Document contains both versions, the box parameters can be changed easily, the tolerances and angles will probably be a bit trickier.
The author remixed this model.
Increased height so Volcano Nozzles fit
