The best 3D printing projects are the ones that aren't just fun and easy to construct, but are also functional. And this cool-looking clock certainly fits those criteria. Unlike most clocks, this 3D printed 'Holo Clock' features a two gear trains, each one moving an arm around (one for hours and the other for minutes). It's a clever and unusual design that is still very easy to read.

The 'Holo Clock' has been designed by Ekaggrat Singh Kalsi, an Indian designer and architect specializing in modern and functional designs. He takes these principles and interests into the world of 3D printing, and his clock definitely reflects that.

But it's deceptively easy to construct. All of its parts are 3D printed, except a handful of screws keeping everything together and a single stepper motor the designer bought in surplus. This stepper motor (a 1:30 geared motor working at 12v with a 3mm shaft, though you can use any similarly sized model) is driven by an ATtiny and uln2803 circuit programmed with Arduino.

To build your own Holo Clock, simply print out Ekaggrat's STL files that can be found on his Thingiverse account, using any FDM 3D printer. While he doesn't provide an assembly guide, the process should be simple enough for anyone with a bit of engineering experience. And after installing your motor and computer board, simply program it with the code Ekaggrat has shared on his GitHub account.

That's all there is to it; just requiring a 3D printer and a handful of parts, the Holo Clock is a perfect 3D printing project for a free weekend. And what project is better than one that's practical, functional, accurate and helps you to be on time?

"Never be late, get a clock!" Solid advice there guys!
