PDGA measurements (mm)

Shape character

Flat top (print-ready) — perfectly flat top, STL exported top-down: drops into the slicer with no rotation and no supports. Dome & shoulder roll ignored.

Material (solid print)

Densityg/cm³ — match your filament spec sheet

Print factormeasured ÷ theoretical — even "100% infill" prints run a few % light

Weight = solid volume × density × print factor. The 0.94 default was calibrated against a real 100%-infill PLA print (167 g measured vs 178.4 g theoretical). Set it to 1 for the pure theoretical weight.

Speed tracks rim width; glide tracks dome height; turn & fade lean on nose height (a parting-line-height proxy) and dome. Fit to the 28 presets — treat as a starting point, not gospel.

Paste these over the top of disc.scad, or download the .json and load it via OpenSCAD → Window → Customizer → “+” (import preset). The estimated weight here uses the identical profile polygon and Pappus’s theorem, so it matches the echo in OpenSCAD.
