Pendulum Clock

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.
