Mathew's Assembly Run

  • 3 injection molded plastic (ABS) parts
  • 2 short screws
  • 2 long screws
  • 1 short black paper liner (5cm x 4cm)
  • 1 long black paper liner (5cm x 8cm)
  • 6 5cm lengths of double-sided tape
  • 1 5cm black foam tape
  • diffraction grating (5cm x 4.4cm) *protective film I did without-- this extra step increases the chances of damaging the grating in order to protect it.
