I needed some spare wall mounts for a few routers. I tried to match it as close as possible. I think it's close enough to work just fine. I couldn't find it for sale or out in the 3d world. So I gave it a shot, and here we are. Mod away if you want to. I hope someone else can use it.
It should only take about 30-35 minutes. Depending on your quality settings, it should only take about 2.38 m and 7.22 g of filament. Internally, I did a support cubit for the infil at 25%. The mounting holes should work fine; you might need to adjust them to your liking and the type of mounting device you want to use. The back is flat and filled, so if you wanted to use a 3M style mounting tape, you could, versus the back of the original mounts that are open. Just some options.
This is my very first posting of a 3d file. I'm new so please let me know how it could be better in future. I used SketchUp for my modeling.
Everything else should be straightforward. Have fun. Cheers!
