Part Cooling with Neopixel

thingiverse

**Info** This is a part cooling system made by [this guy](https://www.thingiverse.com/thing:4211824) along with my approach on hotend Neopixels. **You will need** - 5 Neopixels similar to this one - [Single Breakout Neopixel](https://www.banggood.com/50Pcs-DC-5V-3MM-x-10MM-WS2812B-SMD-LED-Board-Built-in-IC-WS2812-p-963382.html?utm_source=googleshopping&utm_medium=cpc_organic&gmcCountry=GR&cur_warehouse=CN) - a motherboard that can support Neopixels - Soldering Iron - a 3-wire ribbon cable with a connector to fit your motherboard - ready to tweak some firmware stuff - Insulation tape **Installation** - On the blower side, you screw it to your blower fan, the same way the stock blower vent is installed. - On the other side, it holds to the fan box with a small chamfer, make sure to slide it in. - The leds are seated into their slots and then soldered with small wires . You can even hot-epoxy glue them to the printed but, but this makes it impossible to transfer them to a new print. - Cover the wires with some insulation tape. The fan box is metal and could short your leds. - If you are using Skr e3 mini you have to change a small jumper on the motherboard to power the leds. Here is the [SKR documentation](https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/master/hardware/BTT%20SKR%20MINI%20E3%20V1.2/The%20Notement%20of%20BTT%20SKR%20MINI%20E3%20V1.2.pdf) that shows the jumper. **Firmware** - I am using marlin and i had to enable neopixels and flash again - If you are using an SKR mini e3, you can follow [this github solution](https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/issues/123) to get the leds working. This solution implements [this improved Neopixel library](https://github.com/CommandoreBombardiero/Adafruit_NeoPixel) **Designed in** - [Fusion360](https://www.autodesk.com/products/fusion-360/overview) **Firmware** - [Marlin](https://marlinfw.org/) **Hardware** - Ender 3 Pro
