I designed a 3D printable gauge/ruler that can be used to measure the string action on a guitar or ukulele. It features measurements in both millimeters and fractions of an inch. It can be optionally printed in two colours (does not require a multi-colour capable printer). Or print in single colour and use a sharpie to fill the depressions.
I could not mount the D’Addario Planet Waves clip free guitar tuner (model PW-CT-21) onto the headstock of my travel guitar. The headstock of the guitar is so small that there is no way to attach it so that it would not interfere with the left hand. I designed and 3D printed this custom mount for the tuner to solve that issue. The mount places the tuner in between two tuning machines, raising the tuner just above the machines. The mount attaches with the two long wood screws supplied with the tuner.
I am sharing this design in the hopes that it may be useful to someone else. It is fully parametric, and, most likely, you only need to change one parameter – btwn_mounting_holes_oc, which is the distance between the two tuning machines mount holes, on center, measured as accurately as possible. You may also want to increase the height parameter if the mount is not tall enough, and the tuner does not clear the tuning machines.
