This 3D Printed Clock Writes the Time with a Marker

, ,

 

Plotclock is a clock that uses a marker to write the time on a small whiteboard. When the time changes, the clock erases the previous time and writes the current one.

The open-source design was made by joo, a user on Makerbot’s Thingiverse, the world’s largest online design community for discovering, making and sharing 3D printable things.

People around the world have already attempted to make their own version. You can find a small gallery here. Since plotclock is open-source, others have already begun ‘remixing’ and modifying the design. You can find a small gallery of ‘remixes’ here.
