Scratching pad that sits at a slight angle for cats who like to scratch rugs or mats. My cat prefers these to posts. It's designed to fit 6mm sisal or hemp rope, which can be replaced when worn out.

I used M4 screws and nuts to secure the ends of the rope. M3 screws and nuts to hold the sides in place. The main body and sides were printed in 2 parts and glued together. To finish, I added small rubbers pads from Amazon to stop it sliding on a tile floor. Estimate of ~20m of 6mm sisal rope to cover.
