Summary

This guitar pick grip is supposed to assist an individual with holding a guitar pick in the traditional grip (pick in-between thumb and outside of index finger, with remaining fingers curled towards palm), but with some extra support.

You WILL have to drill a 3mm hole through the top of your pick.
You WILL have to print the pick sleeve from TPU.

The red piece, the pick sleeve, was printed from Ninjaflex 85A TPU on a FlashForge Creator Pro. The infill was 20% gyroid with 2 walls. Print this piece standing upwards so there will be no need for supports. The infill and walls dictate how squishy/flexible the sleeve is.

The handle was printed from PLA at 20% grid infill and regular supports on.

You will need a panhead M3x6mm screw and 3mm hex nut. You will thread the screw through the pick and pick sleeve, then tightened with the hex nut on the opposite side. The image above shows where the hex nut goes.
