Dust port expander for the Parkside (lidl) belt sander.
It was specifically designed to fit a Nilfisk rubber nozzle but may fit similar.
The port opening is 36mm across with a slight taper.
This does require support. I found it worked well with the nozzle opening on the bed and just placing support in the slot around the top.
