Summary

Convert standard 24h wall clock movement to a slow 24h one-hander.
Uses an HM-12 Micron movement.
Yet never printed.
PLA printed in 0.12 layer height. Needs some adjustments for center-to-center gear distance and small gear design as it doesn't print neatly. Big gear and frame print well.
Added gear STLs with larger pitch for better printing, as small pitch gears have some interference in meshing when installed.
Removed small pitch gear STLs as they are unusable without heavy filing.


ToDo:

  • transform OpenSCAD file to a parametric customizer (not now)
  • add weekday hand
  • design an hour hand with a quarter hour vernier addon (printed, tested, the hand is too heavy for a standard movement)
