I could not find correct size for mine purposes. So i designed my own in Tincercad based on the one from OSSY House.

It kinda works. Its not making work totally dust-free though.

Sponge size: 100 x 68 x 27 mm

Vacuum hose internal: 32 mm

I found 90 degree hose connection better solution.

It fits thight, you may use duct tape if leaks on hose are too big.

To make it easier to print, its splited into diffrent parts and need to be glued togheter.

You only need supports on hose connector.

Models that are uploaded are slightly diffrent from those in photos. I fixed cover issue.
