Skil belt sander to shop vac adapter

This is for a Skil 7313 belt sander. It may fit other models as well. I need to be able to hook it up to dust collection/shop vac so I made this adapter. It goes from the Skil rectangular fitting to a 2 1/4" dust fitting. The one I printed is really tight on the shop vac side, but I didn't want it to wiggle off.
Printed at 100% infill out of PLA.
