<p>This is an enclosure for the <a href="https://www.adafruit.com/product/4253">Adafruit Quad 2x2
|
||
FeatherWing</a>.
|
||
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.</p>

<p>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.</p>

<h2 id="parts-i-used-in-my-clock">Parts I used in my clock</h2>
|
||
<p>For my clock design, I placed <a href="https://www.adafruit.com/product/2965">4 displays in
|
||
front</a>, the Quad in the middle, <a href="https://www.adafruit.com/product/3857">a
|
||
Feather M4 Experss</a> and <a href="https://www.adafruit.com/product/3028">precision RTC
|
||
FeatherWing</a> in back. I also put a
|
||
<a href="https://www.adafruit.com/product/3898">small lipo battery</a> inside so the
|
||
display would continue to run during short power outages. Then I used a whole
|
||
pile of <a href="https://www.adafruit.com/product/3299">M2.5 screws (5mm are good) and 12mm
|
||
spacers</a> to put it together.</p>
|
||
|
||
<p>While I haven’t put the clock code online, there’s a series on my personal blog
|
||
