Belt sander dust port

I am lucky that I have a fairly large shed but I still pack a lot in to it.

The dust extraction port from my belt and disc sander is too close to my spray booth. The sawdust would get pushed under the lid of the spray booth and could get stuck to any paint that may have been drying.

To reduce this I have 3D printed a cowl that sends the extract to the back.

I didn't get the measurements of all the angled faces quite right but it works well enough simply held on the end with a double sided sticky pad.
