<p>I stumbled upon this great octoprint plugin:</p><p><a href="https://plugins.octoprint.org/plugins/wled/">https://plugins.octoprint.org/plugins/wled/</a></p><p>Since I use WLED everywhere I designed this little indicator Light.</p><p>I used these WS2812B LEDs with inner diameter 36mm and outer diameter 50mm:</p><p><a href="https://www.amazon.de/gp/product/B07TZK8JTQ/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&amp;psc=1">https://www.amazon.de/gp/product/B07TZK8JTQ/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&amp;psc=1</a></p><p>And an ESP32 D1 Mini</p><p><a href="https://www.amazon.de/gp/product/B08BTLYSTM/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&amp;psc=1">https://www.amazon.de/gp/product/B08BTLYSTM/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&amp;psc=1</a></p><p>The ESP32 fits snuggly into the base.</p><p>A little strip of double sided tape holds it firmly in place.</p><p>For my version I printed out 2 of the LED ring cases and glued them together.<br>I didnt use any glue for the base since it was a good fit there.</p><p>For those of you who haven't fiddled with WLED yet check out Aircoockie's Github:</p><p>https://github.com/Aircoookie/WLED/</p><p>&nbsp;</p><p><strong>Print instructions:</strong></p><p>The diffuser was printed with white PLA, 0,2 layer height.</p><p>The base for the ESP32 and the LED rings were both printed in PETG with 0,2 layer height.</p><p>The LED ring base needs supports from buildplate.</p><p>&nbsp;</p><p><strong>Assembly:</strong></p><p>You will need some wires and a soldering iron.</p><p>M2*4 screws for mounting the rings.</p><p>You can print multiple ring bases and glue the together.</p><p>But for more than two or three you'll need a separate 5V supply for the LEDs.<br>I simply used the VCC pin on the ESP32 board.<br>Max. current should not exceed 1000mA!<br>You can always set a power limit in WLED to play safe.</p><p>&nbsp;</p><pre><code class="language-plaintext">VCC pin → red wire → LED VCC Power Supply GND pin → black wire → LED GND IO2 pin → green wire → LED DI Data Input Connect LED DO to next ring LED DI</code></pre><p>I put some heat shrink over the wires.</p><p>There will be minimal light bleeding on the backside, since it is not completely closed.</p><p>Maybe I will redesign the diffuser since it sits a bit loose.</p>
