Scroll Saw blower / puffer tube replacement fitting

thingiverse

I recently discovered that my trusty Ryobi scroll saw had a faulty coupling attached to its dust puffer/blower mechanism, a black component as clearly depicted in the accompanying photographs. One of the original part's lugs had fractured off, thereby preventing it from securely clamping down on the bellows and creating an airtight seal. To resolve this issue, I utilized Fusion 360 to design a replacement coupling, which is represented by the white component shown in the images. This newly created fitting appears to be functioning properly.
