Guitar / Banjo Tuner Peg Grommet / Bushing

thingiverse

Surprized no-ones uploaded one of these. This is the bushing that goes into the head of the guitar, and guides the tuner. Pictured in a banjo I was working on; on inexpensive instruments these have often fallen out or are missing, and usually only come with replacement tuning machines. There's little stress on this part once installed so 3D printing is a good option. Bushing is designed for 1/4" tuning peg, and a hole a little over 3/8" (0.39, or 25/64ths).
