This is a clock face for someone who really likes coffee!
I made this as a gift and forgot to take a photo of the original finished product.

EDIT: But here now is the second one. This version I was running out of black so I paused the print and changed to brown. Then it was only 1 1/2 layers before the white but the resulting effect looks pretty good.
Also, addd is a hook bracket to be glued onto the back.

The center hole is left small so it can be reamed out to suit whatever clock mechanism you get.
I just purchased a cheap clock and used the works from that. The hands had to be painted as they were black and I used black and white PLA.

This was sliced to have 20 layers.
Add this code between layers 13 and 14 in the gcode so you can change the colour......

G0 F9000 X210.962 Y214.852 <<<<<<<<< last line of layer 13

; begin layer pause code
G91 ; Put in relative mode
G1 Z10 ; Lower bed by 10mm
G90 ; Put back in absolute mode
G1 X0 Y0 ; Zero (home) the X & Y
M84 S0 ; Disable the stepper motor timeout
M0 WHITE then Click To Restart ; Pause and wait for the user
M84 S60 ; Reenable the default timeout
G91 ; Put in relative mode
G1 Z-10 ; Raise the bed back up 10mm
G90 ; Put back in absolute mode
; end layer pause code

It is fun to have the pause code in the gcode to easily change filament coluor.
