Time to escape into the real world
Slice & export
CubbyCAD builds your model as one watertight solid with the Manifold engine, so the exported file matches what you see, with no inverted normals or holes to repair. Export to a standard 3D file or send the model to the built-in slicer.
Use STL for a quick print-ready mesh, STEP when another CAD package needs solid geometry, and glTF/GLB or PLY to keep per-vertex colour. Open Slicer takes you straight to laying out and slicing the current model.
How to use it
Open the Export menu
Open the menu and choose to expand the submenu.
Export an STL
Pick or press Ctrl+E. The whole scene exports as one STL right away.
Pick another format
Choose , or from the same submenu.
Export a single group
Select the group and use in its Export section of the Properties panel. In the Export dialog, set a File name, pick a Format (STL, STEP, glTF / GLB (colour), or PLY (colour)) and click Export.
Slice for printing
Choose . The slicer opens in a new tab and gets the current model as an STL automatically.
Tips
- STL and STEP carry geometry only. To keep the per-vertex colours of imported parts, export glTF / GLB or PLY (marked "(colour)" in the dialog).
- Export always runs at full quality. If Preview Mode is lowering on-screen detail, the exporter rebuilds at full resolution first.
- The slicer is a separate app in a new tab. If the scene is empty or the browser blocks the pop-up, it won't get a model, but you can still upload an STL there by hand.
- Set an Export name in a group's properties to pre-fill the file name for a group export.
- STL is always free. STEP, glTF and PLY are Enhanced formats. Picking a locked one offers the upgrade and falls back to STL.
