Tevo Flash Nozzle LED light holder

thingiverse

Inside my printer enclosure it's difficult to see what's happening during the evening unless I change the color of the LED lights inside the enclosure to bright white. This isn't very pleasant to watch from the couch, so I decided to create a holder which fits three WS2812b LED's. I've connected the LED's to a NodeMCU and control it with MQTT and Home Assistant, but I guess there are other solutions to control the LED's. I've made two versions. The behind the carriage version is as it says, behind the carriage and the BLTouch - it's the version you see in the pictures. The below the carriage version will be 2.5mm lower, making it the same height as where the nozzle gets thinner. I haven't tested the below the carriage version myself yet, as I prefer it being hidden, and you don't actually watch straight into the light of the LED's. To install the LED holder, you have to unscrew the hot end and the BLTouch to get it over the hotend mount. The screw holes on the LED holder are lined up with the screw holes of the BLTouch, so you just have to screw back the BLTouch with the holder in between. Be careful not to over tighten the screws. I kept the holder as thin as possible to minimize the weight on the carriage. The LED's come with double-sided tape on them, so you can just stick it to the holder. I've printed the holder with PETG, which doesn't get affected by heat as much as PLA. The code for the NodeMCU can be found on Bruh Automation's GitHub page. Big shout out to him for this awesome piece of code - I'm using it all over my place to control my LED lights. https://github.com/bruhautomation/ESP-MQTT-JSON-Digital-LEDs If you like this thing, please consider clicking on one of the affiliate links below: Tevo Flash: http://bit.ly/2PGVo0w NodeMCU: http://bit.ly/2R4pNG3 WS2812b: http://bit.ly/2CuOjfK
