Replacement guitar string pins
I designed and 3D-printed some replacement pins for my guitar strings, when several broke on me. Onshape document inside!
This week, I restrung my guitar. But to my dismay, as I worked out the first peg to remove the low E string, it cracked in half! I got my beautiful blue acoustic/electric thinline guitar online for $60, almost exactly a decade ago, so I never had high hopes for its quality. Even so, I was a little surprised.
Fortunately, it was nothing that a little experimentation in Onshape couldn't fix. The shape was pretty easy to nail, and on my third try, I got the taper just right to fit my guitar's bridge holes. You can download, copy, and tweak it via the CAD document here.
I printed these fast and dirty in PLA; they take under 10 minutes in 0.3mm layers, including support material. (I laid them down horizontally, so the layer orientation gives them strength.) Then I did some minimal, lazy finishing by clipping down the layer edges with flush cutters, so the taper wouldn't catch on the guitar body.
It's now been about a day and a half, and they're holding strong so far... further updates as events warrant. :) For now, see them in action during Space Song Sunday episodes!
