The ASUS RT-BE3600 Dual Band Wi-Fi 7 Router inexplicably has no mounting holes/tabs, so it's apparently intended to sit on a desk or shelf.
I designed this mount to allow the router to hang on the wall, with a pair of holes for screws plus little indented spots for Command Adhesive medium strips.
Pictured mount was printed with Prusament Galaxy Black, 15% infill. When exporting from Fusion 360 to PrusaSlicer, rotate the design around so the bottom part is flat on the build plate, which angles the whole thing a bit.
The mount holes may produce supports, but they aren't necessary: paint them out, leaving the main supports behind.
The author marked this model as their own original creation.
