  1. Identify scientific/engineering lab need on campus for a 3D printable substitute for existing or planned purchase
  2. Meet with users to determine exact needs/acquire additional funds/components for multipart equipment
  3. Design 3D printable components with OS CAD packages
  4. Open NIH 3DP account and post: STL, include all source files from OS CAD package, directions, explanation of what it is and a price estimate for a commercial equivalent (can use Appropedia page for directions and main host if easier)
  5. Print component and bring to class (online students print and send to my office/place in box outside of door)
