shackcad.com Visit website

Editorial interest 77/100 Selection signal · not a rating of the site

A Mac CAD app for 3D printing, with editable solid models, sketching tools, and STL or 3MF export.

Landing page captured for the 2026-10-20 issue.

For: Mac users designing parts for 3D printing
Worth noticing: The page describes an Orbit gearbox as fifty editable parts, while a later section shows a 16-part 3MF export.

Field notes

The described workflow includes sketches on XY, XZ, or YZ planes and directly on flat faces, with dimensions and relationships to position profiles. The page also describes Boolean operations that preserve both operands, allowing a cut feature to be resized afterward. It says the printer outline is only a reference and does not clip or scale the model.
