Version 3 is here:
https://www.thingiverse.com/thing:3596998

This is a 3D printable isomorphic keyboard piano overlay, designed to fit over top of an existing standard piano keyboard. It rearranges the notes to a more logical layout.

The keys pivot around a "metal round" which can be purchased at hardware stores.

There are 19 keytops per octave.

Assembly instructions, once you've got the parts printed out, are here:
