This is basically a guitar pick with an integrated finger grip. In the center of the pick, there is a circular indent with the letters '3D' raised up from it. This bot serves as a way to show people how cool a 3D printed guitar pick can be, and it provides a grip so the pick is less likely to fall out of your hands while playing. In one of the pictures there is a bottle cap for size comparison next to the pick. The number 3 in the pictures is slightly more bulging than the letter D, but that wa because my filament got clogged a bit in my printer. I have printed others that look perfectly fine (I gave them to a friend, so I ddon't have them right now). This is a 100% original 3D model, and actually feature a slightly shorter and wide design than most guitar picks, to offer a better grip. Thanks for considering me for the free filament offer! (by the way, I used transluecent blue PLA, just in case you wanted to know. In addition, it ony took 9 minutes to print, so it's super fast! It was printed on a Rostock Max, a standard FDM printer. This model has not been uploaded anywhere else.
