A bracket for upgrading the Creality CR-X with a BLTouch, designed to work with stock hardware. offsets are 30mm left and 39mm front, I use 40mm margins. Although these are large margins, it is a compromise to keep the bltouch clear of airflows.

To find your true offsets pick a point on the bed and mark it somehow at the nozzle location (corner of a piece of paper works fine), then move the bltouch to that same location while counting the mms.
