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.
Meet the custom mount
I quite liked the way the mount worked out. The supplied mount attaches with one screw only, and will probably swing around that screw and require periodic repositioning. My mount attaches with two screws, which means that it will always stay exactly in the same place.
The mount consists of two parts – the platform and the plug. The platform attaches to the tuners. The plug keeps the tuner in the mount. I dropped a small piece of rubber under the plug (which I cut out from an old bicycle tube). The rubber applies a bit more pressure to the tuner’s base and makes it a bit more sticky when rotated in the mount.
Everything prints without supports. I used PETG, but PLA should also work.
