The CRUX 1 is an excellent little printer, but could use a BL Touch as my bed was warped. I installed a glass bed, and an SKR Mini V3 into it, so a BL Touch is the next logical step as far as upgrades.
This mount works well, you are unable to probe the right 25mm of the bed, but this was the only mount that could work without overhauling the entire hot-end assembly. It mounts right over the 40mm hot-end fan, no additional hardware is needed. The M3 screws holding the fan into the carriage are long enough.
