Miter saw vacuum hose adapter

This is my first attempt at a shop vac connection to my old miter saw.  The saw is quite old and a generic brand from Harbor Freight but still works well.  The adapter that came with it did not fit my Rigid brand shop vac which has a 45 mm hose OD.  This adapter fits the saw port and expands out to accommodate the larger shop vac hose.  My may post an update as the hose does not seat very far into he current design and may need to be longer.

I printed in PLA with 30% infil.  I did use supports around the base ring where it fits into the saw and has a small groove.
