This clock is 230mm in diameter with a 9mm hole for the clock stem to fit through. There is a square piece on the back side for the clock mechanism to fit in. I made this approximately 60mm x 60mm so that any clock mechanism should fit. I printed this on a X1C and the print profile worked just fine for me, but you might find better settings to use on your printer. I'm still pretty new to 3D printing.

I would greatly appreciate it if you could rate my models and profiles, Thanks
