A clock face with hollow numbers.

thingiverse

This is a prototype clock face with hollow numerals that may require some adjustments. The main clock face view appears to be distinct from the front-facing perspective, which still needs refinement. A more printable version of the design can be found in the latest clock-face.stl file. On the other hand, the clock-face-sp.stl file incorporates the numbers into the overall design, resulting in a larger material requirement for the printer but potentially fewer loose parts during assembly. When complete, this clock measures approximately 5 inches in diameter.
