I needed a low profile mount for a Biqu Microprobe V2 on my current toolhead setup, this has been designed to fit behind my modified backplate for Bosco Lau's magnetic cooling duct. It should clear their original design as well.
This bracket works with the fasteners included with the Microprobe, as well as the ones that would have come from your factory cooling duct on your Ender 3.
I have the z height set up for a Phaetus dragonfly BMS, I haven't tested the factory MK8 hot end.
Offsets:
X -35
Y -5
I have my Z-offset around the 0.93 mark, YMMV
