How cadgent dials in a fit

The loop behind the HS-02A insert: cheap physical sweeps, a few sharp rules, and a refusal to call anything "fits" without holding it.

01

The fit-gauge loop

One continuous clearance against a physical object: measure with calipers, print a thin-ring gauge that sweeps the diameter, find the snug ring by hand, bake that number into the real part, reprint once. A gauge is a few grams; reprinting the whole part per guess is not.

02

The tool stack

No single CAD kernel. Whatever measures or cuts the geometry most honestly for the job.

trimesh
mesh edits, cylinder-fit, sections, booleans (manifold3d)
OpenSCAD
parametric bodies + headless renders
admesh
manifold / degenerate / parts checks
Bambu CLI
headless slicing to real print time
03

The verification discipline

Claims are tiered by evidence, and the tier is never upgraded for free. A render proves a render. Only a printed, measured, hand-checked fit proves a fit.

An adversarial print-readiness gate runs before any "ready." Its job is to disprove the claim, not bless it. If it can't, the verdict stays UNPROVEN, and so does the part.
