What CubbyCAD is
CubbyCAD is a browser-based 3D modeler for designing parts intended for 3D printing. It is presented for people who have moved beyond Tinkercad but do not want a long learning process in Fusion or Blender. Models use solid and hole shapes combined with boolean operations that the site says create watertight results. Tools include sculpting, parametric modeling, sketching, extrusion, revolving, lofting, smooth blends, editable mirror and array modifiers, rigging, and posing. Parts can be scripted in JavaScript or TypeScript, with settings exposed as sliders. CubbyCAD imports STL, OBJ, GLB/glTF, FBX, and 3MF files. Export options include STL, STEP, glTF, and PLY, with some formats requiring Enhanced. A built-in web slicer opens separately and receives the current model as an STL; its documentation calls the slicer experimental. Workspaces can use browser storage, a local folder, or cloud storage after sign-in. Browser and folder workspaces are free and unlimited. The Free plan costs nothing, while Enhanced is $6 a month, billed monthly.
Who it suits
CubbyCAD suits makers designing printable parts who want browser access, parametric tools, scripting, and a free starting plan. It also fits users needing local or browser workspace storage.
