Simple Gear Example-Inkscape to Openscad

thingiverse

Make gears using Inkscape, OpenSCAD, and a 3D printer with these steps: 1. Open Inkscape to create a new document, set units to inches, and use the Gear tool. Specify number of teeth, circular pitch (24px), pressure angle (20°), and click Apply & Close. 2. Convert the gear object to a path by pressing [Shift+Ctrl+C], select nodes, insert new nodes, and make selected segment lines. Fit page to selection in Document Properties. Save as .dxf file (Desktop Cutting Plotter - R13 type). 3. Open OpenSCAD, load .dxf file using linear_extrude(file = "something.dxf", height = 10, center = true); and combine multiple .dxf files if needed. 4. Add a cylinder for gear attachment in the center (e.g., 1/4" dowel or Tony Buser's pin connector). 5. Compile and export the file, open in NetFabb to repair if necessary, and then import into ReplicatorG for printing. 6. For a second gear, use 14 teeth with the same circular pitch and pressure angle as the first gear. Calculate center distance (CD) using CD = (N1 + N2)/2P. 7. In OpenSCAD, create a base large enough to fit both gears and drill holes for gear attachment (use dowel or Tony Buser's pin connections). Adjust hole spacing based on calculated CD. 8. Compile, export, repair if needed, and print the final design.
