Thunderbolt Cable Lock, OWC ClingOn Compatible

A generic take on the OWC ClingOn.

It helps to greatly reduce USB type C/Thunderbolt connector strain and provides friction to resist cables being inadvertently disconnected.

Use a M2x20 hex socket or pan head screw to screw into OWC products (Thunderbolt chassis, docks, etc.). For other products, you will have to cut double sided tape to size, or glue if don't mind a semi-permanent installation.

If printed in hard plastic, connector friction fit varies from cable to cable, but I got a nice friction fit with generic Thunderbolt cables that came with OWC, HP products and LG monitors.

If you need a tighter fit, I recommend warming up the flat side opposite the screw hole using a hairdryer or heat gun, then squeezing gently to warp the part slightly inwards.

This print works just fine with 0 infill and 2 shells. Print with the flat side down (opposite to the side with the recessed screw head hole and filleted plug entry).
