4" Hose to 2" Dust Collector Adaptor

I made this adaptor to connect a 4" diameter vacuum hose to the 2" opening of my dust capturing system. Maybe you need it?

Print version A or B to match the thread direction of your hose... although it still worked when I got it backwards :P

I printed with ABS for longevity. A nice wide 15-20 perimeter brim held it down while printing. Printed solid.
