65mm 800w watercooled spindle dust shoe

I have created, based on a number of designs online, a dust shoe that mounts on an 800w WC CNC spindle. I have yet to find a free design out there for us.

This is currently a work in progress. I have posted all the source files for you to use and modify.

The part where the screw tightens at, is a very weak spot. If anyone could figure out a way to fix that issue, I'd be very grateful.
