I redesigned the original Prusa z screw cover in Fusion 360 to have a movement indicator. It's meant to be printed with a color change, where the second color starts at height 5 mm.
With Source file
I have added the .f3d source file as I hope more people would add source files to their things. Often I want to modify a thing and having only the .stl file it's more cumbersome than it should be in my opinion. So I don't want anybody to get frustrated when they want to modify my design.
0,1 mm height and 0,4 mm nozzle
Printed in PETG but PLA should come out cleaner.
I did a color change during printing to make the movement indicator more visible (second color starts at height 5 mm).
When printed with PETG some stringing cleanup might be necessary.
Screwing might be a bit hard at the beginning, but it's getting easier while screwing.
