Large Numbers Clock

This model is for a wall clock with an approximate size of 210mm x 210mm (8.25" x 8.25"). It is intended to be a 2-color print. The NumberClock_rec.stl file has recessed numbers and requires the use of an MMU or AMS for a 2-color print The NumberClock_raised.stl file has raised numbers that can be printed in 2-colors by pausing the printer and changing colors just before the small numbers and ticks are printed. I guess the clock could also be printed as a single color but I'm not sure how that would look.

I printed with supports on set to snug. It prints faster with normal supports versus tree supports on my slicer settings. I also printed with 2 wall loops and 12% infill. Turning ironing On improves the look of the clock however lengthens the print time. My photo of my print is with ironing off.

There are numerous clock modules available with various shaft length and diameters. I purchased mine from Amazon. The clock module measures 2.1" x 2.1" or 56mm x 56mm. The body of the clock module is 0.65" or 16.5 mm thick. The total shaft length of the clock module is 0.47" or 12 mm with a brass shaft length of about 0.24" or 6.4mm.  These don't need to be exact and small variations are OK. The brass shaft diameter is approximately 0.29" or 7.4 mm.

The hour and minute hands are optional. You can of course use the hands that came with your clock module instead. Different clock modules have different diameters for the hour and minute shafts. I used what I believe to be the most common; 0.22" or 5.65mm for the Hour Hand and 0.15" or 3.84mm for the Minute Hand.
