  1. 3D printing

Print bottom cap, top cap, PiCam holder, and spine with our green PETG. The .stl files and .gcode are located here

  1. Exoskeleton (composed of carbon fiber rods and lexan)

To fabricate carbon fiber rods:

  • cut 4 wooden rods to 16.2cm each
  • once the rest of the structure is verified, cut 4 carbon fiber rods to 16.2cm each (since there is not much spare)

To fabricate lexan:

  • 3D print PETG cylindrical mold (the lexan has a 13cm inner diameter, so the PETG cylindrical mold has a 13.0 cm outer diameter)
  • cut flight lexan to 40.8cm length and 15.9cm height
  • apply heat to lexan with heat gun and mold to PETG cylindrical mold, holding in place with clamps (put cloth between clamp and lexan to avoid scuffing)
  • weld together both ends of the cylinder with super glue at seam and supplement with rectangular PETG piece for extra support
