UPDATE: Files for this clock are uploaded. Let me know if you have any questions.
A true remix of the popular TheGoofy mechanical clock. I took the gearing and reconfigured it to work as a pendulum controlled format.
I have added a few improvements to the drive system, the biggest being 3x7x3 bearings on most of the gears to reduce friction down to a minimum. The entire system uses 3mm rods and most of the system uses 3mm x 60mm rods which you can purchase off Amazon so very little cutting is needed to assemble the clock.
I added a second drive gear connecting to the winding drum to reduce the amount of torque that a single gear was creating in the system.
I increased the thickness of the perimeter of a few of the gears slightly so printing would be somewhat improved.
I am currently re-evaluating the re-winding process to improve the efficiency of the process.
The clock face is designed so that up to 4 colors can be used during the printing process by switching filaments at specific print levels.
I am currently running 7lbs of weight to drive the clock. I will most likely be redoing the pendulum weight design since when the clock weight travels downward the pendulum has caught up on the weight cable on a few occasions.
The only lube I have used on this is a little white lithium on the escapement wheel tines so the pendulum escapement fork glides back and forth smoothly. I also added a tiny bit more to the hour/minute/seconds gear shafts so they would not have much friction between them.

In my test build I have used ABS, PLA and PETG filaments in various combinations for visual purposes.
I used a 12" piece of 8-32 threaded rod for the swinger assembly.
I used (1) M3 10mm self tapping screw through the swinger clip.
I used M3 self tapping screws for connecting the top and bottom frames and also holding the clock face in place.
Fine tuning of the swinger is a matter of slightly adjusting the swinger clip position on the swinger escapement fork until the back and forth movement is evenly timed in both swing directions.Fine tuning the time is done in two ways. First you adjust the swinger weight up or down the threaded rod until you get the timing to be right. I used a small binder clip to ultra fine tune the timing by adjusting the clip up or down the threaded rod to change the weight distribution point.
