The 25 mm aluminium coupler that drives a lead screw or threaded rod from a stepper motor's shaft: rigid at 20 mm across, or flexible at 19 mm with four slits that take up misalignment. Each half is bored for its own shaft, 4 to 10 mm — 5 to 8 puts a NEMA 17 on an M8 rod or T8 lead screw — round or D-shaped for a motor's D-cut shaft, and clamps it with two M3 set screws at 90 degrees, the first of them down on the flat.
