ESD Wriststrap Grounding Point - wall mount

I have a multi-purpose workbench, and couldn't find wall mount ESD Wrist strap grounding point. Most are meant to be installed under the bench, but that isn't an option for me.
I bought a cheap 2 port ESD ground socket. https://www.aliexpress.us/item/3256806185522431.html
Then replaced the housing with this printed version.
