MOST Delta filament as guide.JPG This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printing

Please leave comments using the discussion tab. The course runs in the Fall semester. It is not open edit.


  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)
  6. Add picture, link to NIH in gallery, "savings per replica" and a hyperlink to cost source on Appropedia below.

Link to Mill Collet Holder Prototype on NIH 3DP


  • 20% Print quality
  • 30% Documentation
  • 25% Design (design for printing, plastic minimization)
  • 25% Function - Does it work? (e.g. could it actually help teach someone something)

Automatic reductions: -50% no source or the use of non-OS software -10% per day for late
