Woodworking models can be exported as 3D-printable assembly kits
Published on
Export assembled models or packed loose parts for 3D printing, including supported hardware.
The Export menu’s 3D print option prepares a scale model as an assembled object, loose parts, or parts held on breakaway rails. The dialog provides bed dimensions, scale, clearance, and an STL preview.
Rail packing groups repeated pieces and shares rows among one-off shapes. Review the preview and selected scale before downloading the STL, then inspect the file in your slicer before printing.
