3D printing can be a fun and productive hobby and skill, but there can be a lot of confusion around the files involved. Here are some you should know about.

12:12 pm August 11, 2021 By Julian Horsey Holo Clock is a unique clock created using a little 3D printing and Arduino hardware and coding by Instructables user “saulemmetquinn”.

If you want to build your own, [ekaggrat] posted all of his design files on GitHub. All you need is a PCB (or breadboard), a few components, and a bit of time on a 3D printer to make your own clock.

They are learning. The Plotclock is a small, 3D-printed clock that forgoes the traditional gears and springs for servos and an Arduino microcontroller. It writes the time. And then erases it.

Autodesk's Tinkercad is a free Web-based design tool that enables you to create 3D objects, then download those creations in a printer-friendly format. Here's how to get started.
