Old door latch actuator

Door latch actuator - 3D print model OpenSCAD

On a particular old door latch mechanism, the doorknobs are connected to a square- profile axle that engages with an actuator whose arms push the latch.

The cast steel actuator's arms have broken off -- probably because of stress concentration at the sharp angle where the arms meet the body.

This actuator replaces the cast steel actuators. The relative weakness of the plastic is compensated by the larger bulk of the part. The plastic is also more quiet and smooth-acting.

Print 100% with your favorite material. I used PETG.
