Mimimalist Digital Clock

A minimalist digital clock that can be built with off-the-shelf components. 

Designed around the MAX9219 4 module display unit, this will print without supports.

I recommend you use PETG (or at least PLA+)

For a full write up about the project, please see this blog post. The code I used is available here.

Assembly

To assembly, I used 2 M2.5x20 mm socket head screws to attach the front bezel to the main body. The screws will bite directly into the plastic. For the rear cover, I used 2 M2.5x5 mm countersunk screws. 

The display will fit snugly into the diffuser, and the diffuser is sandwiched between the front bezel and the main body.
