Here is my remix of the NeoMatrix 8x8 Word Clock from the Adafruit website. It has a 3d printable clock face, case, diffusers and buttons to set the time. I left a slot in the bottom of the case to allow access to the programming port of the Arduino. The OpenSCAD source (in+all-it's+gory) is included if you want to make adjustments as is the Arduino sketch I modified for the time setting buttons.

I printed the clock face and case in Black PLA and the diffusers in White PLA on a Printrbot Simple Metal using 0.2mm layer height and 2 top, bottom and Perimeter Shells. For the clock face I used 50% perimeter overlap and gap fill to keep the light from the NeoPixels from bleeding through the face. For other colors you may want to increase the thickness of the faceplate.
