Self-Latching Sprung Hutch Door Catch
A print-in-place spring catch for rabbit hutches, chicken coops and cabinet doors. It screws to the frame with four #6 wood screws or M4 screws (4.5 mm holes). The angled tongue gets pushed in as the door swings shut and springs back out to lock it, and a thumb tab pulls it back to open. The body is 67 x 42 x 10 mm, the tongue reaches 14 mm past the body, and every moving face has 0.5 mm clearance.
