(12/12) Less than 50 years later, thanks to @marcuswu's hard work, you can now 3D print your own Curta. Absolutely incredible. (the end!)

(11/12) Curt Herzstark's craftsmen were still building Curtas as late as 1971, when electronic calculators finally killed the Curta.

(10/12) how long before someone prints a 3D-printed curta that's printed in one step, fully assembled and ready to calculate?!?

(9/12) how long before someone prints a normal-sized Curta? How long before ALL the internal parts are 3D printed? And hardest of all,

(8/12) @marcuswu's Curta is 3x normal size and includes a few non-3D-printed springs and ball bearings, and it makes me wonder,

(6/12) And somehow, @marcuswu has done it. This is truly a tour de force of design and craftsmanship: thingiverse.com/thing:1943171

(5/12) now treasured by collectors like myself. The Curta is the Mona Lisa of calculators. How can someone 3D print the Mona Lisa?!

(1/12) So I'm a bit of a mechanical calculator aficionado, and I also regularly use 3D printers, so I feel qualified to comment on this...

@GreatDismal Did you see @marcuswu's 3D-printed Curta? As a Curta owner and 3D printer user, I'm blown away: thingiverse.com/thing:1943171
