Why is the case laser cut rather than 3D printed?

• Because 1940s radios were made of wood. IMHO, the device is usable because it is familiar to people whose memories of the 1940s and 1950s are much stronger than recent memories. My Dad was immediately able to use it, saying that it "felt familiar". And I think the wood helps with that.
• Inexpensive. A company will laser cut the case for you for $28.

But I would like to try doing a 3D printed case. If you read the discussion page for this project, you'll see that Dave Neff made a 3D printed case. He made a larger version of the dementia-friendly music player and added speakers. Nice work. I'd like to try making a regular-sized 3D printed case. A key reason that I want to try this is that there seems to be a small army of makers with 3D printers that just love to make things for themselves and others.
