Used PLA and printed at 0.1 layer height. You could change the filament out before the intial is printed for a cooler looking pick. I've tested the pick out and I like it just fine. I will make some more designs later. If you need help with Tinkercad and wish a certain letter I will assist you. If you're printing it for a friend and they play heavy metal, you'll probably want to increase the thickness by 1/3 or to 0.12 in tinkercad.
