I wanted to level my Printed of my Printmate3D with a BLTouch. For this I needed a mount direct to the Extruder head. This fits good to my Printmate, depending on what kind´d of Heartbreak you use (longer or shorter) you you can scale this in the z-axis. Sadly you really need to try this out, you don´t have much space to get the BLTouch working correctly.
You need to drill two holes into the wooden clamp for the Hotend, but this is no problem. All holes are for 3mm screws.
If you have any questions don´t hesitate to ask.

Here is a Video of the working BLTouch:

Supports are necessary, but you can try without if your bridging settings are really good.

I printed with Prima Select PLA white, 200°C on Nozzle, 45°C heated bed, 35mm/s, 0.2mm layer, 100% infill with Support using 3dLac and Simplify3D.
It is an easy part to print and works really well.

Clean the part after printing and be sure that the surfaces where the BLTouch is mounted and where this mount is screwed to the wooden part are clean and flat.

I used Fusion 360.
