Something I designed to be able to have a shower without holding the head.

The two main parts are joined by a Hirth coupling (teethed discs) that are locked together with a printed screw.

Designed to be glued to the wall.

Print instructions

Print with 0.2mm max, as the screw has a fairly fine thread.

Print everything once. Discs friction fit into the slots. (Might need a tap with a wooden mallet/hammer)

Caution: The design uses non-tolerance cuts for tight fits. Please make sure your printer is properly calibrated
