I exchanged the original throat of my Geeetech I3 Pro B for a larger one (M6x50mm) therefore I had to modify this original design made by Zull. The intention of this new design is to keep the expected distance of 8.3mm (+/-0.2) between the base of the BLTouch and the tip of the nozzle. The total height of this piece is 12.5mm.

I use the design up-side-down since I noticed I get very close to the desired height. What I did was to increase the thickness of the base a couple of millimetres. I also get easy access to the screws.
