Instructions

Files:

• Goggles_AndroMEDa_C-Mount_v1.stl: The goggles 3D model with a C-Mount
• Goggles_AndroMEDa_Hook_v1.stl: The goggles 3D model with a Hook mount
• Goggles_AndroMEDa_Glasses_v1.dxf: DXF file for the PET sheet cutout
• Goggles_AndroMEDa_Cutout_x6_A4_v1.pdf: PDF file with 1:1 scale paper PET sheet template cutouts

Materials (per goggle):

• 25 grams of TPU Plastic 
• Any glue that can bind both TPU and PET.
• 1 Rubber band or any other elastic band with appropriate length and stiffness to ensure a proper seal between mask and face.
• An adequately large PET sheet.

Steps:

1. Print the face shield as instructed in the Printing Section.
2. Cut the PET visor as instructed in the Cutting Section.
3. Assemble as instructed in the Assembly Section.

Printing:

• The prototype prints were printed on a CR-20 Pro with TPU plastic. Setting changes may be required to print on any other 3D printer.
• The STL file is to be printed with the side where the PET is mounted facing down.
• If the goggles do not match the profile of your face try printing the design on a slightly higher or lower scale. 
• Settings:
  • 5% infill
  • 0.4mm nozzle diameter
  • 0.2mm layer height
  • 2 wall layers

Cutting:

• The goggles have been designed with a visor as per the shape defined in the DXF or PDF file.
• To ensure flexibility the PET pieces must have a gap between them (about 4mm).
• NOTE: It is not a problem if the PET sheet does not fall directly on top of the outer profile of the goggles as long as the existence of a gap is ensured.

Assembly:

1. Glue the visors to the 3D printed part using appropriate glue.
2. Wait for the glue to cure completely.
3. Attach the elastic band to the attachment points (C-mount or Hook).
