SawStop to Rigid Shop Vac Adapter
thingiverse
Dust collection adapter from SawStop (4") to Rigid Shop Vac (2-1/4"). The diameters match up well. I'm a bit skeptical about that 2.5" spec - it looks more like 2 1/4". You may need to adjust the model to fit your setup perfectly. The diameter dimensions are clearly labeled in the Inventor part file.
