This is an attachment to allow anyone without a left hand to enjoy playing the piano. It attaches to the Skipping Rope Attachment (https://www.thingiverse.com/thing:2876195) and by simply rotating the wrist, it allows you to arpeggio one octave in the major and minor scales on all of the white and black keys! It is a very simple design, but very effective. Check out the video links at: https://youtu.be/G8ZgsKlDXXg
Aurarum PLA, TPU
The LH Piano Adapter is made from PLA, and the optional tips are made out of TPU to reduce noise on the keys.
