Conventions
* Body length: One house length per size: the whole mm the makers' stated lengths round to, the most makers' within 2 mm, the longer on a tie. Backed by the makers listed on each page; no one maker's value.
« Where makers differ: The largest stated square, pilot height, shaft length and through hole, so a bracket made to the model clears every maker's motor; each maker's value is on the page.
e Body and caps: Three solids: black end caps and the silver laminated stack, their corners cut, a seam at each end of the stack; on frames 23 and 34 a thinner front flange and the body's corners cut back clear of the through holes. Illustrative, not any maker's design, checked for fit only.
e Holes, shaft and rear: Tapped holes as plain bores at the thread's nominal diameter, 1.5 x that deep; the shaft's end chamfered; a shallow round recess in the rear face; a 4- way connector in one side of the rear cap; a label with the CommunityCAD mark. Illustrative.
e Body length 40 mm is a house length (#1227 item 2 A): the whole mm the makers' stated lengths round to. anaheim-17y: 39.878; leadshine- cm-steppers: 40; moons-hybrid- steppers: 39.8.
