This gantry adapter is specially for use for the biqu hermit crab using a bltouch. It solves the problem I found that you had to use 2 additional pieces to mount the bl touch and it would be far out to the left of the hot end. I found that this print improves the usable print area and you want the bltouch as close to the hot end as possible.
The bltouch mounts directly to the gantry adapter.
