Reasons to own a 3D printer - Guitar Practice
I designed and printed this part of the guitar neck for a person starting to learn how to play guitar. This is used practice changing cords without having to pick up a whole guitar. This was particularly useful as a beginner as it was quick and easy to pick up and practice with and also helped strengthen my fingertips. I was able to design and print this within a couple of hours of thinking it would be something cool to make. This goes to show the power of owning a 3D printer and if owned a printer you too could do countless things like this.
