This is a simple clip that holds the glass for the Carrera glasses in the frames. The original clip disapeared after a drop, so I designed this as a replacement part. It is stuck on with friction like the original.
I printed this with a 0.6mm nossle but a 0.4 might be more appropriate for the small details that are on this part.
I used PETG since that has some flex to it for the friction fit around the glasses frame.
The author marked this model as their own original creation.
