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. Solidworks file is included in this model; you can use OnShape's free version to edit as needed.
