The Dustshoe that came with the Millright CNC machine I use didnt work for me. At first i printed an attachement that let my Vac hookup to it but the suction was poor.

Here are 2 deisigns:

The old one is basic and accounts for a 1.25 dia vac tube to fit in and be close to the router spindle.

The final one is a bit more bulky for strength and is also adjustable for height to get suction at max.
