DIY retrograde clock is 3D printed
Retrograde clocks are unique, in that they avoid the normal fully circular motion for the hands. Instead, the hands simply sweep an arc segment, before returning to their starting position to start over. They're pretty rare to find, but [Jamie Matthews] decided he had to have one. So he chose to build his own!
For his build, [Jamie] started with a standard standard clock movement that you would find in any hobbyist clock build. From there he affixed his own mix of cogs and witch gears to the outlet to create the desired semi-circular mechanism. The arcane mechanism allows the clock to read the time in an arc of approximately 180 degrees.
It's also relatively simple to create one yourself. The parts are all easily 3D printable, with [Jamie] reporting that it took less than 8 meters of filament to produce the gear train for his build. You can even print the clock face if you don't want to CNC cut it out of acrylic.
All in all, it's a fun look at an often overlooked part of our horological history. Desktop 3D printing really makes it possible to create different and exciting clock designs. Video after the break.
