I wanted something clean and simple to put on our wall. As shown on the pictures, the clock has a diameter of around 75 cm. It is super easy to print and don't use much material.

I used this cheap quartz movement: https://www.banggood.com/DIY-White-Hands-Silent-Quartz-Wall-Clock-Movement-Repair-Parts-p-958127.html

The "lines" are mounted to the wall with double-sided tape. I used a laser level, an inclinometer, a string and a nail to put them at the right location and angle.

The holes in the hands are a bit smaller than they should be so that you can adjust them with a file to fit perfectly to the movement.
