Self Playing Guitar Servo Bracket

thingiverse

This is a customizable fret servo bracket for the self-playing guitar project by one hacker band. See them in action here: https://www.youtube.com/@onehackerband These are made to use standard-sized servos. What works for me: I print them in PLA on their side on a raft with 20% infill and supports at a high angle so the slicer doesn't fill in the mounting holes. The mounting holes for screwing into the neck are 4mm in diameter. I use four #4 wood screw for this. They need to be short so they won't interfere with the truss rod. The holes for the servo are 5mm in diameter. I use #6-32 threaded heat-set inserts for these and then short #6-32 socket head machine screws. **Notes about the customizer** The *width* of the bracket is between the two sides with the mounting holes. This should be the width of your neck at the specific fret you're working on. Be careful, this measurement can change as you up/move down the neck. The *depth* of the bracket is the measurement between the center of the mounting holes and the top of the cross brace. I try to position the mounting holes right between the wood of the fretboard and the wood of the neck. Be sure to leave yourself enough room - it is **not** vital that the cross brace touches the back of the neck, but I try to get it close. The *chamfered braces* option just allows you to remove the chamfered supports between the cross brace and the bracket. I just included this in case a strange neck shape was making things not work for you. Please let me know if you have any issues or questions!
