This is a slight improvement to a TP-Link Deco W6000 AX3000 Wall Mount I used but wanted different sized screw holes and cleaned up ends. It will also fit TP-Link Deco X20, X55, X60. This design link has great tips for how to print and mount it but I didn't need a brim but your milage may very, https://www.thingiverse.com/thing:4948160 PLA, PLA+, PETG, etc.
Got mine mounted above the TV but hidden behind it! I apologize for the print job the filament because it sat awhile and looks rough!
