32-21 day feature for new small 8 day clock

Steve.

Thanks for 14.1 mm diameter spool for your new small 8 day clock. It's slightly different from the 1" spool in that there is no arbor projection on top of the gear. I don't know if this is by design. BTW, I've got all the small gears printed and the teeth came out perfect on my lowly Ender 3S1. I plan to run it in 8 day mode first, because hanging 8-9 lbs of weight on it may result in creep.

Thanks, Gary

That's awesome to get 32 day mode for the easy build clock. I ran mine with that configuration for a few months before dialing it back to either 10 or 14 day mode. It is much more reliable now.

There are a few ways to increase runtime on these clocks. The ratios of gears 7/8 or 7/4 can be changed, winding barrel diameter can be changed, or extra pulleys can be added. We should ignore silly solutions like hanging the clock near the ceiling or cutting a hole in the floor to give more drop on the weight shell.

The new 8 day clock does not have room to increase gear 7 or 8 to increase runtime. This only leaves winding barrel diameter or extra pulleys. Both solutions will require more turns when winding the clock. Reducing the barrel diameter is the easiest solution. The lower limit is set by the 3mm rod spacing. It should be possible to double the runtime. I will try to make the edits in a few days. There are a few other requests for this clock that I also want to add.
