3D Adapt Model-Fit Calculator

Free browser-based calculator for checking a model’s bounding-box dimensions against a 3D printer’s rectangular build volume. Tests six axis-aligned orientations or a fixed orientation, with configurable XY and height allowances. Includes printer presets and a custom volume option, visible formulas, manufacturer sources, and orientation results. No mesh upload or account required. This is a planning check, not mesh collision detection or a substitute for slicer validation.
