777 OSH Science project 2019
Assignment
- Identify scientific/engineering lab need on campus for a 3D printable substitute for existing or planned purchase
- Meet with users to determine exact needs/acquire additional funds/components for multipart equipment
- Design 3D printable components with OS CAD packages
- 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)
- Print component and bring to class (online students print and send to my office/place in box outside of door)
- Add picture, link to NIH in gallery, "savings per replica" and a hyperlink to cost source on Appropedia below.
