My result. Works for 10 minutes with PLA Mainspring. Will be switching to PETG Mainspring once I get my spool. I noticed that once all the minute and hour transmission + outer rings were put in, the assembly was not as smoothly rotating as in the tutorial video even though all the gears printed perfectly. Must be printer inconsistencies, but that's normal I think. Thank you so much Dan for all your effort in putting this toegether. Cheers!
