Could not find a mount for the MX5300 Wifi 6 so I modeled up my own.
I just added a corner mount for the mesh routers too. I did use supports on this mount for the long overhang.
I printed without supports and it works. I got a bit of drooping at the top of the open area for the cords. It wasn't terrible but if you want perfection, then do supports for that area.
The author marked this model as their own original creation.
