Printed with Polymaker PETG on a Bambu H2D. Very fun clock. Printed the pinion gears a different color from the wheels since metal clocks use brass wheels on steel pinions.

Had to replace the reed switch, but everything else is functioning great. Both PETG clocks continue to run flawlessly.
On the reed switch topic, the ones I bought are very fragile glass and very close to the length where the leads have to be bent to go through the housing. I broke several shaping the leads before installing them in the clock. These were 20 pcs for $10, at this point I would pay $10 for one really good one.
I am noticing the pivot that holds the motor and the adjustment knob has a good bit of flex. That one might have to be upsized to 3mm. Any other pivots I should inspect more closely?
I played around with the optional parts including the deadbeat escapement. As stated in the instructions it takes less weight to run the deadbeat but the difference is pretty amazing when you build it. If the motors are the weak point, switching to the deadbeat has to help.
Besides playing with the optional parts I made a few color changes. The trigger on the motor housing is now lime green to show it off against the black motor housing. The pendulum bob is also lime green because nothing else was white other than the numbers.
And for assembly lessons learned, cutting the pivots a little bit short is better than a little bit long.
It would be interesting to hear how well PETG performs relative to PLA. All of my experience is with PLA. My research indicates that PETG should be slipperier but possibly softer. Maybe the gear teeth would like the lower friction, but the rest of the gears would prefer the stiffness of PLA.

PETG is working well so far for this clock and the SP14 Moon Phase Clock.
I had to upsize some of the shafts to 3mm to get it to work, the small shafts kept bending and binding. Also added ball bearing to the 3mm shafts.

Great colors.
