Small Pendulum Wall Clock

myminifactory

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 have been released as premium designs. Significant changes have been made to make the new designs more efficient and easier to build.

The file is 3d_clock1_frame.dxf.
