MK8 BlTouch clip

This little clip lets you cable tie a BLTouch to your mk8 heatsink.

These numbers are pretty close, depending on how your MK8 is oriented.
-12 // X offset: -left +right [of the nozzle]
-35 // Y offset: -front +behind [the nozzle]

As for the Z offset, you will need to probably tweak the file at some point as all nozzles distances are pretty different on these extruders.

Here is the Fusion file, just edit the one dimension on the right side. Easy.
