___________________
Grease from the z-axis lead screw would often get into hands/arms when getting finished prints from the printer.
Design a shield that would cover the lead screws but not affect the printer functionality.
This lead screw cover might not work on the P1P/P1S.
Print as oriented.
Model has built-in support. Remove supports after printing.
Part clips to the z-axis lead screw bearing mount. Optional: Add 8x3mm magnets.
Left and right shield are mirror of each other. Flip in the x-axis in the slicer to print the other. Alternatively, print using the provided left and right profiles.
Variances in the unit assembly. I found it myself that there are variances in the assembly of the units that may affect the fit of the shield esp. on the left side. See picture below. You can see on the left (blue) that the lead screw mount is flushed to the vertical post of the frame compared to the one on the right (light brown). This makes the shield pushed against the print bed support and might not fit well.
Curved edge. If you happen to get the printed part from the print bed when it's not fully cooled down yet, you might have a curved edge. This will cause the print bed support to rub against the curved edge of the shield.
