There only appears to be one valid STL file in the zipfile (the one that's being previewed on this page). There are 3d models for the other parts (white keys, black keys, base and extras) but they don't appear to be valid - neither Slic3r nor Windows 10's 3d model viewer can load them.

Hi signaturefish,

Files check ok. Try using Autodesk123D to open source files and meshmaker for .stl files. Autodesk123 is free and can be used to convert to other formats.

Huh, weird. OK, well, thanks for checking. I'll go get a copy of Autodesk123D and have a play :)

No problem. It is kind of weird that stl failed. All I have is Autodesk 123D. Let me know if i can help further .

Cheers

Thanks , I will check the files

To actually make a keyboard, you need n copies the current design, plus one full octave ending in a C, or just one individual C.

Keys in an octave on a piano:
In an Octave or Perfect Eighth, there are 12 ( 13 if you count the eighth). For scales that begin on white keys, there are always 8 white keys and 5 black keys in a single full octave. For scales that begin on black keys, there are always 6 black keys and 7 white keys in a single full octave.

An octave is 8 notes (C to C). You only have seven, i.e. not a full octave.

It's 12 notes c to b with sharps. Sections are put together on a board . You can start at any point or drop keys as you wish.. I had thought about the "true" octave design but it doesn't translate to modular design very well. Stringing 5 mods together as they are would result on only losing the last C. In which case I would only need to print one last C key section.
