Mshievitz wouldnt want to make you draw over the holiday.
I think the best way to go would be to add an 2 parts, one that converts your existing ir mount to BL/BT/3d-Touch (There are knockoffs already) and one where it replaces the IR mount. There is a set of standard mount stl's on thingiverse that could be easily mesh blended. what is the ball distance center to center. I have some carriages i gave printed that may work
Mshievitz Interested in a version that would support the bltouch/bt-touch
Also radial layer fans for better airflow
