PROBLEM

Grease from the z-axis lead screw would often get into hands/arms when getting finished prints from the printer.

SOLUTION

Design a shield that would cover the lead screws but not affect the printer functionality.

IMPORTANT NOTE (Please read first!)

As the tolerances in the assembled unit varies, this lead screw cover might not work on your printer. See item #1 below in the Tips for Success section. The left side of the printer has very little room to fit the shield and if you have a really skewed printer frame, the shield could rub against the print bed assembly. I noticed this difference between the two (2) X1C's that I have. You can try the thinner version as it might fit better to your unit over the regular version.

Lastly, this requires a really calibrated filament for the part to fit. Over extruded filament will cause the part to be thicker and very tight while under extrusion would make the part thin and loose. Please do NOT rate the model low because it didn't fit well to your unit, which may have really skewed frame or your filament isn't calibrated correctly. A lot of people have successfully installed this shield and continue to use it today without issues.

PRINTING DIRECTIONS

1. Print as oriented.
2. Model has built-in support. Remove supports after printing.
3. Part clips to the z-axis lead screw bearing mount. Optional: Add 8x3mm magnets.
4. 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.

TIPS FOR SUCCESS

1. 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.
   
   
    
2. 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. 
   
   

MATERIAL RECOMMENDATIONS

• Use high temperature resistant material like PETG, ASA or ABS as PLA might warp overtime.
