A tubular nylon spacer with a counterbored end. Model it (or compute it), then report the volume and mass. Miss the counterbore and your mass comes out too heavy.
📋 Scenario
Stores want a weigh-check to catch wrong spacers without a CMM. To set the accept/reject weight they need the true mass of a good part — including the Ø13 × 3 mm counterbore that clears a cap-head screw. Compute it from the drawing and the material.
🧱 Material
Nylon PA6
1.14 g/cm³
📐 Dimensions
20.0 mm
8.5 mm
10.0 mm
Ø13.0 × 3.0 deep
🎯 The check
Model this part (or compute it by hand), then report its volume and mass.
If your mass matches the target within tolerance, your geometry is correct — a wrong
hole, fillet or thickness will always show up as the wrong mass.
