Printed Clocks

I decided to redesign the lower pendulum arm on the SP7 clock. I just got tired of looking for my hex screwdriver and also can't see that well any more to see the hex screw not to mention trying to get the screwdriver down the back to the screw lol.... so I created a M3 thumb screw and created a space for it so you can easily adjust the bob from the front or the back. Placed a little spot on the top incase I want to count turns
