It is a remix of Soozafone's design https://www.thingiverse.com/thing:2702736/

I have created this to fit the base_hinge into a glued wall mount solution from amazon.

It mates with the part that is glued to the furniture on the wall and you can link the rest of the stand to it. No drilling, no stand required.

Print flat on the back. Sometimes need support for the pin to go into the stand brackets.
