I absolutely love that Josef Prusa includes spare hardware with his products. To date, I have built 3x Prusa MK3 printers, 3x MMU2 units, and then upgraded them all to 'S' which has left me with a ton of various M3 screws.
I recently decided to organize all of my accumulated Prusa screws so I designed this simple little tool for quickly measuring each screw. If you happen to find this tool prior to building your Prusa printer, have a friend print it for you - it will make your assembly much easier.

The uploaded photo with the two-color print was a single STL modified in PrusaSlicer using modifier slabs. In addition to the STL, I have also uploaded the two-color 3MF project file in case someone wants to print in multiple colors. I also included GCODE for the Prusa MK3S/MMU2S using PLA in 1 and 2.
