Fine Adjustable Cuckoo Clock Pendulum

This is a remix of https://www.printables.com/model/1144806-cuckoo-clock-pendulum-fine-adjustment-regulator
It's a fine adjustable pendulum for a cuckoo clock. Instead of a friction fit pendulum bob which offers coarse adjustment, this pendulum offers a threaded nut which can minutely tune the bob.
Changes I made to the original include:
- point the end of the shaft to look better and make it easier to thread
- lengthen the pocket on the bob to shift center of gravity so the pendulum is not leaning forward
- reduce diameter of nut so it slides behind the bob
I offer two adjustment nut heights: full size and half size. The full size will stick out and show at the bottom of the bob but is easier to grab and adjust. The half size is totally hidden behind the bob but may be harder to grab. Alternately, the half size nut may be used under the full size nut to act as a "jam" nut to lock it in place.
