Load your model ONCE — a parametric form (dome, vault, saddle, waves, cone, peak) or your own STL/OBJ/PLY/.3dm — and switch how it gets made. Waffle notches interlocking egg-crate ribs; Contour stacks numbered chipboard layers with a registration score; Print prep checks bed fit, suggests the least-support orientation, flags overhangs and gives clearly-labelled rough time/material estimates. The Waffle and Contour math is the exact engine from the legacy tabs.
Runs entirely in your browser — nothing is uploaded. Waffle and Contour export SVG cut sheets sized in real millimetres (hairline = cut, blue dashed = score); import them at 100%. Print prep is an honest pre-flight, not a slicer — every estimate says how it's made (method notes in the tool).
