I have a new design that is all pla, runs for 48 hours and uses some of the original designs but most have changed like mirroring one of the gears so that the pendulum does not hit the weight when they get close together, stay tuned. Mike
I used the design from https://www.thingiverse.com/thing:3149176.
I changed the frame from filament to wood, then changed the large gear so it would run for 26 hours and a rewind for the weight. Here is where I got the idea for weights: Penny Weights for Mechanical Clock

I printed all at .3mm, then bought some pine and that was about it.
