CASIO SK plastic keyboard replacement/3D printing

[wax+wire]

Hi all

From playing aggressively, the keys on my Casio SK are getting weak.  I've snapped one key, and another is on the way out.  Does anyone know what keyboards, other than other casio sk or concertmate use the same comb of keys that might be easier to come by?  Or has anyone ever 3D printed a comb of keys.  It seems to always be the black keys for me.
