I printed this guitar pick in red and blue PLA and also in glow in the dark PLA                                                                                                                       

Print settings: Infill doesn't matter, the pick is too small to have any. I did find that sometimes the bottom layer wouldn't stick to my print bed but this can easily be fixed by adding a brim in your slicer. If you have any questions/inquiries please leave a comment and I will try to reply with an answer as soon as possible.
