In order to use the BLTouch we need a way to mount it. There are some simple brackets available that work with the stock hotend assembly, but we also want to swap the fans and add an LED light strip, and improve the fan duct. Therefore, we'll be using the Hero Me mount which has numerous configuration options.

HeroMe Ender3 Hotend Mount - I've printed the option with the BLTouch adapter, and the single 5015 fan duct. There are other alternatives for replacing the hotend shroud. You can even leave the stock shroud in place and just replace the fans.

Start the disassembly by removing the 2 retaining bolts for the stock shroud and pulling it away. Be careful not to pull too hard on the hotend heater and thermistor wiring.

The hotend fan and part cooling blower can then be removed from the shroud. In our case these will be replaced and the wires can be cut as shown in the following step.
