Mini Cookie-Cutter Apple

thingiverse

Another mini-cookie cutter for the set. Print Settings Printer: DaVinci 2.0A Duo Rafts: No Supports: Doesn't Matter Resolution: 0.2 Infill: 90 (full) Notes: I've printed it with 90% fill, slow speed, 0.2 stepsize, normal wall-thickness and model slices in the XYZware with these settings. Note that slicing should give you a double-wall with no holes. I used ABS. How I Designed This Done in Blender 2.76 by manually drawing the shape based on a bitmap and using extrude and solidify-modifier plus mesh-cleanup steps. Sliced in XYZware giving double-walls without holes. The ZIP file contains the STL file, but also the resulting 3w file and the original Blender file for modification. Blender Details • Start with scene, delete default object (in Edit mode) • Add "shape" bitmap in Z-projection (optional) • Create vertex loop (CTRL clicking), closed • Scale such that 10 Blender units represent 10mm • Clean-up loop (add/remove vertices), smooth etc. • Duplicate object (in Object mode) to have one for "upper" and one for "lower" part • Extrude (in Edit mode) lower part 3 units downwards • Ensure face-normals point outward (Recompute normals if needed) • In Object mode, apply "Solidify modifier", no offset, thickness 0.3-0.7 • Extrude (in Edit mode) upper part 10 units upwards • Ensure face-normals point outward (Recompute normals if needed) • In Object mode, apply "Solidify modifier", no offset, thickness 0.07-0.2 • In Object mode, select both parts, then File/Export as STL Solidify modifier thickness might need adjustment (0.09 to 0.15) depending on how the slicer creates the walls. It should create a double-wall with no gaps!
