A fully parameterised cable management tray / cable holder for mounting under a desk. Includes screw holes or you can attach it using double sided tape.

40 and 75mm wide versions included (both 100mm long) along with the 3mf file if you want to make different sizes.

Note this design is quite rough as it's not meant to be installed in highly visible locations, so I didn't include any edge chamfering etc.

Best printed standing on one end, I used PETG with a brim.
