3D-printed Holo Clock
Analogue-display clocks have been around in one form or another for centuries. Now, with 3D printing, it’s possible to design things that just wouldn’t have been possible even 20 years ago. With this circular design (the maker describes it as a halo clock), maker saulemmetquinn has turned clock design upside down. It’s still recognisable as a clock, with a round face, a big hand, and a little hand, but there’s something refreshingly different about this design that we like.
The gear shafts are brass rods, cut to size using a Dremel, and the current design has a few exposed jumper wires. The whole thing is driven by an Arduino Uno and a stepper motor, with the frame and gears printed in white and black PLA.
