Final Project Assignment

1. Identify scientific/engineering lab need on campus (ideally yours) for a 3D printable substitute for existing or planned purchase -- reserve it on List of Projects below
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. Log in to NIH 3DP account and post STLs, and include all source files from OS CAD package. Then on Appropedia make a landing page and post directions, explanation of what it is and a price estimate for a commercial equivalent as well as links back to the NIH.
5. Presentation on 3-29, Print components, build and bring to class if possible
6. Add picture,link Appropedia landing page and "savings per replica" and a hyperlink to cost source on Appropedia below. Due 4.13.2018
