Browin piston sealing ring.

I had a problem with my Browin 1.5 kg sausage stuffer, silicon piston is a bit smaller than tube and meat escaping from it bacwards approx 30% of load during stuffing. So i made a sealing “sock” to prevent it happening.

Print only in TPU! 

Use random seam selection. 

Use tree support, normal support impossible to remove. 

Make sure before print that walls are there because it's only 0.45mm.
