This is a 3D printed pendulum clock with an 8-day runtime and an accuracy of 1-2 minutes per week. The primary goal was to make a functional clock. It needed to be accurate and still be running if I go away for the weekend. It also needed to look good. This clock achieves those goals.
This design is mostly 3D printed. A few hidden metal components are needed to keep friction low enough to support an 8-day runtime. My clock has been running continuously for over a year and a half.
This clock is based on my design that was posted to a different site. New upgrades will be posted here. The escapement and gears have been completely redesigned for 3D printing. Looking at my older clocks, I realized that the designs were mostly ported versions of old style brass clocks. Significant changes have been made to this new design.
A short video of the clock in operation is at https://www.youtube.com/watch?v=imYTm0Vh5TA
Total print time is around 90 hours on a Prusa MK3. The largest components need a 250mm x 210mm x 200mm print area (Prusa MK3S) or 220mm x 220mm x 200mm (Ender3), but are also included in pre-split versions to fit build volumes as small as 180mm x 180mm x 100mm. Total filament is around 0.75kg PLA in multiple colors.
Comprehensive assembly instructions are included in the files.
Larger and more impressive clocks will be released soon as premium designs. A sneak peak can be seen at https://www.youtube.com/watch?v=kn1OaGAae5w

All files print without needing supports. My default print settings are 0.4mm nozzle, 0.15mm layer height, 4 perimeters, 30-50% cubic infill, random seam positions, and 0.1-0.2mm elephant foot compensation. I have only tested the design in PLA.
