I wanted one that I could quickly remove the supply from as it's on a long cable, and I often take it with me (plugged in or not). Command strips seemed like a better solution to screws but I included holes for a couple of those too, just incase. The strips "cavity" is recessed so you can get to them as I use the hook and loop ones and might not want to break off the bracket when moving stuff about later.

The print that's in the photos is in A Olive Green PLA+ Matte or something like that, its not great to print with for me 80% of the time, particularly at height for stuff like this, hence the nasty stuff, I didnt want to reprint because I really dont need to make any changes so glue it was! I dont -think- it was the model's fault, but your milage may vary.
