This is a rendering of a partial assembly of IPC'S exchange phone.
The front housing of IPC's exchange phone, formed aluminum.
The exchange phone assembly with the circuitry in place.
For CID this was the heart of the project, an elastomer button field. Not at all uncommon but I needed to prototype a functioning model in a month. Hard tooling was out of the question time wise. ARRK Creative Network made an STL for me then cast a urethane mold. They then poured a silicon rubber elastomer to produce the part. To make it functional they painted the simulated "carbon pills" with a carbon ink to make the electrically conductive. They delivered the button field to me in less than a week.

CID, IPC Exchange Phone
I had a background in the Financial Telecommunications Industry. Having designed Trading Turrets (phone consoles) for trading houses (remember Lehman Brothers?) and phones for trading floors. IPC contracted me to fast track a trading floor phone to compete with my old company's product.
