/** NEMA23 rear-adapter profile, with the arc-point technique used by
 * techmannih/nema34-mounted-stepper-controller. Dimensions come from the
 * STEPPERONLINE ST-M10 rear adapter; exact motor rear fit remains unconfirmed.
 * Unlike scaling the NEMA34 outline, this uses the NEMA23 reference geometry.
