Description
This is a 3D printed pendulum clock with an 8-day runtime and an accuracy of around 1-2 minutes per week.
The primary goal while designing this clock was to make it functional as an accurate time keeper. It has a deadbeat escapement which remains accurate with variations in weight or power train friction. I wanted it to have a long runtime so it would still be keeping time if I was away for a few days. It took a few refinements and a few internal metal components to reduce friction enough to allow an 8-day runtime.
Print instructions
Printed in PLA on a Prusa MK3 single extruder. Layer changes were added for highlights in the front frame and dial.
Complete build notes are included in the zip file.
02-Mar-2025 Update: Cleanup revision. Gear profiles updated for better printing. Pallet and escapement spacer sizes were fixed. Back frame passthrough hole enlarged for better clearance. Build notes updated with most recent information. This release now matches the version on MyMiniFactory, although MyMiniFactory also includes many premium designs that are significantly easier to build.
