Well, here is the harpsichord. I designed it as a DXF, converted it to PDF, then textured in gimp.

in researching the harpsichord I decided to add a sound board, a photo of a soundboard, scaled, printed in B&W, cut to size. I also found an actual under lid painting that seemed too good to pass up, The monster chasing the damsel. Rescaled, printed in b&W and cut to size.

I used the keys from the kit's piano.
Next, print the harpsichord stand, and the doors, which are I have designed already.
The to finish list: The swordfish, the polarbear, the elephant leg ashtray, the bird cage, a seat for the harpsichord, and the peacock chair. I may add the whet stone and axe, a two headed tortoise, and a suit of armor. I haven't found samurai armor to co-opt yet, so that may be out.
