title: Feather Quad 2x2 Enclosure
|
|
---
|
|
This is an enclosure for the [Adafruit Quad 2x2
|
|
FeatherWing](https://www.adafruit.com/product/4253).
|
|
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.

## Print Settings
|
|
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](https://www.adafruit.com/product/2965), the Quad in the middle, [a
|
|
Feather M4 Experss](https://www.adafruit.com/product/3857) and [precision RTC
|
|
FeatherWing](https://www.adafruit.com/product/3028) in back. I also put a
|
|
[small lipo battery](https://www.adafruit.com/product/3898) 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](https://www.adafruit.com/product/3299) 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](https://emergent.unpythonic.net/01595078470)
|
|
* [Minimal Time-Zone Handling for CircuitPython](https://emergent.unpythonic.net/01595021837)
