dust port shop vac adapter

thingiverse

This adapter transforms a 1.5" dust port to a 2.5" (nominal) hose, or vice versa, via a straight-thru fitting.

Note that this design is based on the 90-degree elbow version but offers a straight fit while maintaining the same fitting dimensions (seen in the attached image, these are internal measurements), and requires no support material!
