I've always wanted one of these, and decided that I would make one. this one is ~125 mm across the front. I have a 48" airplane propeller that I want to mount it in and hang on the wall.

The small lettering, marks, and numbers in the clock face are .2mm high, while the larger ones are .4mm high.

Edit 11/17/2017: Added a revision A clock face. This revision offsets the black and white stripes in the adjustment window to become printable at different levels.
