You will need to print the glasses and two arms, which connect to the main body with a piece of 1,75 mm filament of any type. Prints very well with PLA but you can try any filament. Feel free to remix this model or if you want me to modify it let me know. I'd be glad if you let me see your makes. Hope you like the model!

EDIT: I added a smaller model with more tolerance where you have to put the filament, since the hole seemed to be too small
