Stackable Nozzle Holders

Material:  PLA, PTEG, etc
Layer height:  0.1 to 0.2 mm
Supports:  None
Skirt/brim:  None

STL, 3MF and G-code files for 0.25, 0.4, 0.6 and 0.8 mm Prusa nozzles with the size engraved on the top.  They stack whether full of nozzles or empty.  The finer the layer height then the more legible the size markings on the top, obviously.  I just used a white indelible pen to make them more readable.  Nail varnish or paint would do fine.  

Not much else you say, really!
