This is an enclosure for the Adafruit Quad 2x2 FeatherWing. It is designed to accomodate a stack of 3 boards with regular height headers, but you can easily change the height by editing the OpenSCAD file and regenerating it.

Designed for 0.4mm extrusion width. Overall, this is a very forgiving print. However, a manually added support under the opening for the USB plug won’t hurt.
Parts I used in my clock
For my clock design, I placed 4 displays in front, the Quad in the middle, a Feather M4 Experss and precision RTC FeatherWing in back. I also put a small lipo battery inside so the display would continue to run during short power outages. Then I used a whole pile of M2.5 screws (5mm are good) and 12mm spacers to put it together.
While I haven’t put the clock code online, there’s a series on my personal blog about some of the surrounding work that went into it:
- Quad CharliePlex FeatherWing hack
- Minimal Time-Zone Handling for CircuitPython
- Calibrating the DS3231 and PFC8523 RTCs
- Helpful scripts for CircuitPython & Real Time Clocks (RTCs)
