This guard slides snugly into place on the top edge of the Prusa Mk3's metal frame, to protect Bowden tubing from being damaged by sliding back and forth across the sharp edge.

For even more protection, apply a layer of masking or electrical tape on top of the guard to smooth out the surface. You can also sand it smooth if you wish.

The length fits within the brackets for my light bar kit, and can easily be scaled up or down depending on your print setup. Print in two pieces if you need it longer than will fit on your print bed.

3D printing recommendations:

• Print in PETG or another plastic that sands smooth easily
• Print with the flat top side against the print bed and the channel facing upward
• Position diagonally to fit on the MK3S print bed, or chop into segments and print in pieces
• Supports not necessary
• A brim or helper discs on the ends may help with adhesion issues
