Assignment

  1. Design something of "high value" that you can 3D print on your MOST Delta
  2. Make sure someone else has not already done it - search http://www.yeggi.com/
  3. Design 3D printable components with ONLY OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)
  4. Create an account at http://www.libre3d.com/
  5. Upload your design under an OS license to Libre3D - include: Source files, STLs, a picture, and a brief description including costs and $ savings
  6. Add picture, link to your libre3D page with name, commercial equivalent link+cost, and economic savings to table below (see example).
  7. Print component and bring to class - Complete and due by 12/11

Grading

  • 30% Print quality
