I play baritone saxophone with several different groups and I hate using music stands, but also hate having to use a traditional music lyre with paper music. Because of this, I searched for any preexisting 3D printable holders for my Kobo Libra Colour e-reader and could not find any suitable solutions to attach the e-reader to my saxophone. I wanted to use the Kobo Libra Colour e-reader because Kobo makes genuine parts for its Libra and Clara models available from iFixit and I wanted a device that could be repaired if it was broken during use. I had used a 3D printed phone lyre holder (https://www.thingiverse.com/thing:5648954) before and found it secure and functional so I imported the STL into Fusion 360 and made it significantly taller to accommodate my e-reader's dimensions. I also had concerns that the lyre clip method would not be secure enough to protect my e-reader, so I opted to remove the lyre connector on the phone holder and replaced it with a GoPro-style connector to be used with the fantastic and well-documented Modular Mounting System Arms (https://www.printables.com/model/185322-modular-mounting-system-arms-customizable?lang=en) and M5 thumbscrews and hex nuts. I attached the assembly to my baritone saxophone with a TPU pipe clamp I designed with a GoPro-style connector. The clamp consists of a rigid PETG GoPro-style connector plate attached to the flexible TPU clamp with two 8mm M3 screws and hex nuts.

Theoretically, any attachment with a GoPro-style connector will make this a universal holder for an e-reader (or other small tablet) for any conceivable application. If a clamp is necessary and the feature is cylindrical rather than slightly conical as in my case with the bari sax, I recommend using PETG rather than TPU as it will result in greater rigidity.

Hardware bill of materials:

30mm M5 .80 pitch thumbscrew x6
35mm M5 .80 pitch pan cheese screw x1
M5 .80 pitch hex nut x6
8mm M3 pan cheese screw x2
M3 hex nut x2

This project was completed as a project through the Cal Poly Humboldt Makerspace for Cal Poly Humboldt IdeaFest.
