Swing clasp

thingiverse

Use this piece to keep a hinged thing closed, and easily open it again. 100% 3d printed, no other parts required. Useful only in low-load scenarios where not very much stress will be placed on the hinge. There is a slot in the "bar" part of Swing_arm: to increase reliability of the part, I recommend you glue a small strip of a rubber band into this slot. The rubber band will act as a sort of gasket, creating a nice firm clasp. To use this in your design, simply attach the Upper_body to one side (the lid of a box, for example) and the Lower_body to the other side (the box itself). All parts use a 0.3mm tolerance, which seems to be perfectly fine on my Replicator2. I designed this piece using parameters for all the part dimensions.
