This project is an example of how to use the Paint Editor to create SVG files for 3D printing a cookie cutter. There is no programming involved, just graphic outlines. PAINT A SPRITE COSTUME: Paint a new costume (switch to Vector mode) Create a shape and use reshape tool to form the desired shape DESIGN THE CUTTER OUTLINE: Duplicate the shape and add another slightly wider outline (~1.5 grid squares). Use a thin line width, the plastic will be the space between the inner and outer most edges of the design. Too thin and it will fall apart, too thick and it will smear the cookie dough. ***IMPORTANT*** - DO NOT EDIT THE INNER OUTLINE (black) it needs to be identical for the next step. MAKE THE BASE: Duplicate the costume. Edit the outer outline to be ~4-5 grid blocks in width (not as specific as the cutting outline, but too big will result in longer prints and wasting plastic) EXPORT (SAVE) TO LOCAL FILE (.SVG) Right-click, Ctrl+click, Cmd+click or Shift+click or 2-finger click on Mac to "Save to local file" IMPORT INTO TINKERCAD (or other software) Import the base outline (set height to 2mm) and cutter outline (15mm height) Select both objects and use the Align tool to center them on each other Group the base and cutter. EXPORT AS STL Be sure you have grouped both the base and the cutter and export the grouped object as an .STL file for printing. PRINTING Use your desired printing software to prepare (slice and generate code) for your 3D printer.
This is not a usual way to design a 3D printed file, but because it is simply an outline that needs to be extruded it works. Scratch was chosen because our classes have Thanks to the SPR1P7 & SPR1P8 Computing to Learn classes for working through the workflow. A special shoutout to Sami who helped specifically with using the double outline widths, resulting in saving us an additional step using InkScape software.
