The mount is designed with my very limited skills, but it works. I was able to install the [BIQU H2 extruder](https://3dprintbeginner.com/biqu-h2-extruder-review/) on the [Creality Ender 6](https://3dprintbeginner.com/creality-ender-6-review/) and print at 100mm/s with excellent results.

This was done using Klipper firmware. If anyone needs a guide about this, [I wrote one here](https://3dprintbeginner.com/how-to-install-klipper-on-creality-ender-6/).
