This is a remix of DarioCairoli TP-Link Deco M5 ceiling mount https://www.thingiverse.com/thing:3831153; I have added a receptacle to mount the AC adapter so it can all hang easily from the wall outlet.
The space between the AC adapter and the finger holding the part is just right to put the wire like the picture shows.
DarioCairoli did a fantastic job with the mounting unit, the fingers fit perfectly!
I'm adding the STEP file if anyone wants to modify in their 3D modeling software of choice it can be done easier.
The original cradle was converted from the STL mesh so many surfaces were imported prismatic but it works the same.
I hope this helps someone out there who would like to mount their Deco to the wall outlet.
