This clock was an experiment to see if I could show the time by casting a shadow. When the power's off, the clock appears as a monolithic circle but the detail is revealed when the light is activated. This is a single-color print that would work well with any light-color filament that transmits light well - check the gallery to see it in orange, yellow and white marble.

Assembly Instructions

Attach the switch to the base with using (2) M2x6 screws - orient the port so that it's facing out with room to attach a wire.
Feed the USB power cable through the rectangular space in the back of the back shell. This will be a tight fit and may require rotating the cable to find space. Attach the PH2.0 connector from the power cable to the Y connector Attach the black wires of the Y connector to the switch Attach the red/black wire to the COB LED. Feed the LED through the hole in the base.
Start at the end of the LED and press the strip into the channel - be sure that the front of the LEDs are facing out.
Place the button cover into the slot in the back shell & attach the back shell to the base using (4) M2x6 screws. You may need to be cautious that none of the wires are pinched in the process. It can be helpful to lightly tape them in place so that they are not damaged when attaching the shell.
Insert the back of the clock kit through the base and attach with the brass nut. First place the hour hand onto the shaft of the clock kit (it'll be a tight fit) and then follow with the minute hand.   Press the front shell onto the front of the base. It may help to use a rotate the shelll back and forth as this is a tight fit. Ensure that the hour markers are aligned so that they are oriented correctly. Check to be sure that the hour and minute hands aren't touching the front shell as this could damage the clock kit.
Insert the stand into the back and attach with an M2x6 screw.

Printing Tips

• Use a smooth PEI plate so that the front surfaces (through which light passes) will not be marred.
• Be sure to use a light-colored, opaque filament for the front shell so that enough light can be transmitted. Transparent filaments are not recommended.
• The settings in the print profile are recommended to allow maximum light through the front shell.
  Be cautious when removing the fron shell - since it's thin it can easily break or discolor.

Updates

• January 29th: Updated base to account for spacing of stand.
