These print-in-place frames are designed for Oakley Gascan replacement lenses, which are widely available. If the frames break or get lost, you can print a replacement pair and reuse the lenses. Use ASA or another high-temperature material if you plan to leave the sunglasses in a hot car.
Tips for Printing
Option 1: Upside-down orientation
Orient the sunglasses upside down, with the lens area facing up, and tilt the whole model about 15° relative to the build plate. This helps keep supports out of the lens channels. Use organic supports that start from the build plate only.
Option 2: PAHT-CF with ASA supports
For clean breakaway supports, print the sunglasses in PAHT-CF and use ASA as the support material. If you prefer not to wear carbon-fiber material against your face, reverse the materials: print the sunglasses in ASA and use PAHT-CF for supports.
