This 3D-printed typewriter, made by an inventor named Toast, is a really interesting project, and not in the way you’d expect. Unlike regular typewriters, it skips the usual keyboard and ink ribbon. Instead, it uses a rotary wheel to pick letters, where you select a character and press a key straight down to stamp it onto paper using carbon paper for ink.
What makes it so unusual? The typewriter uses a typebar setup to stamp letters and has a system to shift the paper while typing. But picking letters can be tricky for beginners, since you need to rotate the wheel to select a character and then press a key down to print it on the paper. One other cool feature is that it uses carbon paper instead of an ink ribbon. The typebar basically presses the carbon paper onto the sheet to make an inked letter.

A mechanical system moves the paper after each letter is printed, ensuring the right spacing and alignment for the next one. It likely uses a basic gear or lever system, though the full design details aren’t completely explained.
Most of the typewriter’s parts are 3D-printed, so makers can easily recreate it. The model files are on Toast’s Gumroad page, letting others download and print their own. 3D printing allows for tricky shapes, like the rotary wheel and typebar holders, to be made at home, but the plastic parts might not hold up well under constant pressing.
