Hollow Clock Gear and Hour Hand Esp32 Base

thingiverse

I didn't like the gear that connects to the hour hand. It is flaky because the screw that fits the hour hand might end up spinning freely on it and the screw might tight secure on the gear giving a false sense of tightness. And it has a lot of backlash. Also, I didn't like the idea of the screw holding the hand to the gear by pressure. As mentioned before, the screw might be tight but the hour hand can spin less tight. The change here is that the gear that handles the hour hand has a slot that is kind of square so that the hour hands lays on it almost effortless and there is less room for backlash and miss position of the hour hand. I also made a base to place the motor driver and an esp32. With the base, I made a cover to be glued to the original clock base. Ideally the cover / lid is tight enough to fit the base. You could screw some parts together if you plan to lift the clock from the minute big ring gear. Otherwise, the base might not lift together with the clock.
