This is a wall mount for a Wii sensor bar using large Command strips (not an affiliate link). It has a pocket for the command strips to be hidden. It needs to be printed with a decent amount of support for the pocket, but that gives a nice rough surface for the Command strip to stick to. Plus, if your printer is better than mine at bridging you should be able to print it without supports. Walls and infill are to your preference, but I did three walls and 10% gyroid infill and it was solid. Each pocket is .75" x 4.5625" x 0.1" deep if you want to cut down other styles or brands of adhesive sticks. The depth is meant to use the Velcro-style strips so there aren't any ugly tabs hanging out anywhere. I used PLA, and it stuck fine. Not sure about other plastics, but I am sure PETG and ABS/ASA would probably be fine as well. PP doesn't usually like things being stuck to it.
