This is inspired by some under desk cable organizers I bought that come in a 2 pack. I needed an extra shorter one. Only 10" long so I modeled it in Sketchup. I included the grooves the originals had to dissipate the heat from a power strip. PETG would be better also for heat dissipation. I used some Gorilla double sided mounting tape to attach to the underside of my desk. The originals came with peel and stick adhesive.
