Vacuum LocLine 2-1/2" Coupling for Dust Collection

I wanted an adjustable dust collection solution for my drill press. This solution uses a 2-1/2" Loc-Line [1] mounted to the drill press with a 14" 2x4 [2]. It joins with a regular 2" shopvac hose via this thing (3D printed coupling).

The coupling fits into Loc-Line very snug, so I recommend using hot air gun for 15-20 seconds to lightly soften the Loc-Line while pushing the coupling in. The inside of the coupling is tapered for the shopvac hose to fit in snug, but is also easily removable.

For reference my shopvac is the Ridgid 4 gal [3] and the hose outside diameter is tapered 44-46mm (~1.75").

1. Loc-Line Vacuum Hose Component, Acetal Copolymer, 9 Elements Segment, 2-1/2" Hose ID, 1' Length https://www.amazon.com/Loc-Line-Component-Copolymer-Elements-Segment/dp/B00270GDB6/
2. Drill two 2-1/2" holes about 10" apart with hole saw in a 2x4, then cut it in half length-wise. Use 2 bolts to turn it into a clamp. Now you can clamp the drill press and the Loc-Line in place allowing to rotate the Loc-Line around drill press.
