The metal BLTouch mount included with the Biqu B1 was bent at an angle and couldn't easily be bent vertical, so I remixed this mount. It had too much adjustment for my needs, so I simplified the design which included by recesses to capture M3 nuts and an access hole for the adjustment screw.
Designed for and tested with a genuine BLTouch 3.1, so your mileage may vary if using a clone or a different version.
You will likely need to babystep your Z probe offset to suit your needs, but -1.5 is a good start.
Probe offsets are included in the filename, but they are also listed below:
#define NOZZLE_TO_PROBE_OFFSET { -1.5, -34, -1.5 }
You can find a base Biqu B1 BLTouch firmware in the Marlin Configurations repo. Just adjust the probe offsets as mentioned above.
