Tools needed for fabrication of the OSATEdit

  1. MOST Delta RepRap or similar RepRap 3-D printer

Skills and Knowledge Necessary to Make the OSATEdit

  • basic measurement

Technical Specifications and Assembly InstructionsEdit

  1. Print the top part and down part separately.
  2. Joint them by heater through the edge of each part.
  3. printing time for each part is about 1.5 hours.
  4. Jointing time is about 15 min.

Cost savingsEdit

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimate your costs: about 2 dollar.
