This was made to hold the baby safety gates in my house open and attached to the wall when not in use.
Made for gates with bars 10.5 mm diameter. Distance from wall to outside of bar is 30mm. Scale it up down to your needed size.
IMPORTANT: Do not change model orientation as it is key to its strength.
Attach to wall with tape, glue or skrews. Screw head for original is max 5mm. I just uset tape on cleaned surface. PETG or stronger recommended.
