MPCNC dust collecter adapter

grabcad

I created this based on another design i saw on Thingiverse (https://www.thingiverse.com/thing:3784175). However, since my z-axis pipes extend slightly beyond the stepper motor, it allows me to fit this adapter _over_ the pipes instead of inside them and reducing the internal diameter. I also wanted to be able to screw in my vacuum hose rather than have the adapter fit inside it and then use a clam to hold it, again reducing internal diameter.
