Steve Peterson | 3D Printed Moon Phase Clock @stevesclocks | Uploaded February 2024 | Updated October 2024, 2 hours ago.
3D printed pendulum clock with a large moon phase dial. This is one of my largest clocks with an accurate moon phase dial located at the front and center. It is as large as possible while still being printable on a Prusa MK3/4, Ender 3, or Bambu Lab P1S/A1. Runtime is 7.8 days with an accuracy of 1-2 minutes per week. The moon phase dial is accurate to within 1 day every 2.6 years.
The STL files are available at the following links:
myminifactory.com/object/3d-print-large-moon-phase-clock-362741
printables.com/model/785631-large-moon-phase-clock
The clock follows the same easy to build design style as my other new clocks. The bill of materials has been reduced and the only machining required is cutting the arbors to length. The pendulum components drop into place without glue. The winding key is easier to build and more stable. Multiple size weight shells are provided to allow filling with either lead shot or BBs.
The clock is 9" wide by 22" tall and 6.5" deep (225mm x 560mm x 165mm). The tip of the pendulum is 30" long (760mm).
The minimum printer size is 210mm by 210mm. Total print time on a Prusa MK3S is around 160 hours using 1.7kg of PLA filament. Newer machines will reduce the print time considerably.
A comprehensive 50 page assembly guide is included with the STL purchase, or you can download it from stevesclocks.com/sp14 if you want to see the steps ahead of time. You can ask questions during your build or share pictures on my debug forum at stevesclocks.com/forum
