parallyze shared this project on Thingiverse!

I always liked 7 segment displays. So with absolutely no need to I decided to build one. The single frame was intended to be used inside a picture frame. But then I started playing around with the dual design and ended up building a clock that’ll be collecting dust soon.

Sample code is provided for the single frame only using 15 leds (ws2812b, 60 leds/m).

However, the additional parts (although not pretty) might be of use. The case barely fits an Arduino Pro Mini and a rtc module I had lying around. Be aware of wire gauges depending on how you wire more than one of the dual displays. And if using the stand you might need to mirror it using your slicer, depending on the desired position. For the clock I used 2 (one as it is, one mirrored along y).

Hole spacing of the single 7 segment display is: 59,979mm / 110,004mm

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

  1. And here’s a grid version (5×16) with working sample code for a clock (arduino pro mini, ds3231, ws2812b).
