What is 3D Print Generator?

3D Print Generator is a set of parametric tools in the browser for practical parts. The Box generator makes open-top boxes and bins from length, width, height, wall, bottom and corner radius; the Advanced Box generator builds fitted cases with lids, hinges, latches and dividers. There are also an involute gear generator (tooth count, module, bore, pressure angle), a screw generator for metric and inch screws, nuts and washers, and a grille generator for vents, mesh covers and louvers with mounting holes. Each tool shows a live 3D preview, with print-bed outlines for common printers.

A Text to CAD tool turns a written description of a part into editable OpenSCAD code.

Designing and previewing are free, but exporting an STL needs a Google sign-in and credits from one-time packs: Hobby $14.99 for 300 credits, Pro $34.99 for 1,000 and Studio $79.99 for 2,500. A parametric STL export costs 1 credit and a Text to CAD generation 30; credits never expire.
