He's got the key issue solved, how many 1,000's of parts to go?
I got this from Piano Price Point today, a 3d printed piano made for Pearl River.

Subject: Chuck Behm in the news
Just saw this TV news item re: Chuck Behm's development of a year-round waterproof piano to be donated to Boone, Iowa.
Interesting look at how he developed a key that could survive the year-round outdoor exposure.
Hope this link works:
