We have an Asus Wifi system in a mesh, and we needed to place a router in the laundry room for better coverage.Since it's near the washer drain, I wanted to mount the adapter away from water. I printed it in Bambu Tough PLA.

The AC Adapter measures 48mm wide and 30mm tall. I made it 80mm long and added a cutout so it could be easily moved in and out.

I added screw holes, but elected to go with 3M Command Strips for the time being.
