Door Claw

Self-latching door catch for doors that don't stay open with round handles.

Unlikely to suit all doors with round handles but hoping it will inspire your own designs. I used a piece of cardboard to match the profile and then re-produced it in CAD.

Modelled with built in support to minimise the amount required. This gets removed after printing.

Attach to handle, close onto wall and mark the perimeter of the base (use tape to prevent permanent marks on the wall). A single screw will secure it. Hole is slotted so there is some adjustment.
