Template for a 7-segment digital clock (for use with NeoPixel-style chained segments), printable in place/no supports, Holes for 8mm LEDs. Adjust the Z model scale so that the front of the digits is not thicker than 1-2 layers, otherwise it won't be translucent enough (I printed in black PLA). In my design each digit (and the colon sign) has its own cable, daisy chained across the central hub. An elastic USB cable will do - 2 power wires, data-in and data-out for each digit (and for all segments in a digit) . Originally I used WEMOS D1 Mini to drive the WS2812B LEDS, and to read NTP time from the Internet. I used it also for a digital signage - displaying some crappy scrolling 7-segment alpha text :)
