NEMA 23 To NEMA 17 Adapter Tower
A 62 mm square, 19 mm tall adapter that lets a NEMA 17 stepper bolt into a machine face drilled for NEMA 23 — the base carries the 47.14 mm M5 pattern, the raised Ø52 tower carries the 31 mm M3 pattern with a 22.4 mm pilot register for the motor's centring boss. The hollow Ø30 core clears a shaft coupler, a 14 mm side window gives Allen-key access to the coupler set screw, and counterbores in the base bottom fully recess the four M3x20 motor screws so the adapter still seats flat.
