Duckling Cookie-Cutter

thingiverse

I successfully designed my fourth cookie-cutter model. The exterior rim is a bit smaller compared to the previous one. Print Settings: Printer: DaVinci 2.0A Duo Rafts: No Supports: No Resolution: 0.2 Infill: 90% (full) Notes: I printed it with 90% infill, slow speed, 0.2 stepsize, normal wall-thickness, and model slices in XYZware using these settings. This setup results in a double-walled model without any holes. How I Designed This: I created the shape manually using Blender 2.76, drawing based on a bitmap image, applying extrude and solidify-modifier techniques along with mesh-cleanup steps. Sliced in XYZware for double walls without holes. The ZIP file includes the STL file, the resulting 3w file, and the original Blender file for modification purposes. Blender Details: Start with the scene, delete the default object (in Edit mode). Add a "shape" bitmap in Z-projection (optional). Create a vertex loop (CTRL clicking), making sure it's closed. Scale so that 10 Blender units equal 10mm. Clean up the loop (add or remove vertices), smooth out the mesh, and ensure face normals point outward (recompute if needed). Duplicate the object to create separate upper and lower parts. Extrude (in Edit mode) the lower part down by 3 units, making sure face normals are correct. Apply "Solidify modifier" in Object mode with no offset, a thickness of 0.5 units, and adjust the face normals accordingly if necessary. Extrude (in Edit mode) the upper part up by 10 units and ensure face normals point outward (recompute if needed). Apply "Solidify modifier" again in Object mode with a thickness of 0.15 units and select both parts. Finally, export as an STL file using File > Export
