Found such thing on thingiverse. But did not find way to fix it on the wall. So decided to change it a bit.
Bolt should be printed upside down
Print without supports and rafts
PLA works fine
0.2 layer
0.4 nozzle
Also you can use cura 5 project or find your own settings.
The author remixed this model.
Split this on 2 pieces and make possible to use screws to fix it on wall
