Slide door lock

This is a lock for sliding doors to prevent my kids go out from the room.
You can lock and unlock from either side of the door.
At least 10mm space between the door and wall is needed for this instrument.

Print all of them without support, remove the supporting part from the body.stl product, assemble them and put it on the wall using double-sided tape.

A stronger version is released.
