A small bracket designed to make setting up a BLTouch easier. The block at the end is set to the recommended 8.3mm above the flat of the arm, while the markers on the arm show 15mm (the minimum distance you should mount from heated parts) and 50mm (the maximum recommended offset). The provided hole should easily be large enough for any variant or clone to fit.

To use it, loosely mount your BLTouch (or equivalent) and place this guide on the print bed (cold!). Lower the print head (or raise the bed) carefully, making sure to line the BLTouch pin up with the hole, until the nozzle (also cold!) just touches on the arm. Adjust your mounting bracket and/or add spacers as needed.
