Reusable parametric CAD components
nema17-mount · v1.0.0
Faceplate mount for a NEMA 17 frame stepper motor: a square plate with four M3 clearance holes on the motor's 31 mm mounting grid, a central register bore over the motor's pilot boss, and an optional raised register collar. Dimension sources: the NEMA 17 standard metric drawing (42.3 mm square faceplate; 31 mm × 31 mm M3 mounting-hole grid; ⌀22 mm pilot boss about the ⌀5 mm shaft — NEMA ICS 16 frame family) and ISO 273 medium-series M3 clearance (⌀3.4 mm). The bore default ⌀22.5 mm gives 0.25 mm radial clearance over the ⌀22 pilot boss. Every dimension is a parameter, so other NEMA frames (different grid pitches) and reamed fits build from the same component.
The parameter "plateSizeMm" needs a finite number (mm).

Real Manifold kernel in a module worker. The build rides the same `solid.*` operation vocabulary as the workbench. Volume is the kernel's divergence-theorem measurement; the analytic value is the component's closed-form fixture at the current parameters.
