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 90fill (full), 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!
