By way of Maker Update, I learned about this YouTube project to build a 6x normal size digital calipers wall-mounted shop clock.
There are a lot of good building tips here. I especially liked how they finished the MDF material to make it look like brushed steel. The secret sauce was Bondo on the MDF to achieve a smooth finish before spray painting.
The enclosure for the display and the electronics was 3D printed. Instead of measurements, the display shows the time.
