Prusa z-axis indicator

An easy print for the z-axis to see the finest movement of your z-axis while printing and your Prusa is doing the adjustment to give you a perfect first layer.

It will fit exactly on the conical z-screw covers, if you use an additional dust cap (picture) or not. Mounting is just a clip on, so no disassembling is necessary. 

I recommend PLA and a small nozzle for printing, because of the fine structure of the part (see picture: 0.25n, 0.1 layer)

This one fits perfectly on the conical, z-screw covers (“dust cap”) from the Prusa original setup of a i3 MK3 (S) (+)
