I have a foodsaver vacuum sealer and some zwilling vacuum bags and containers and I wanted to be able to use the foodsaver with the zwilling containers so I made up these adapters. Smaller one works for the containers and the larger works for the bags. Meant to be printed in TPU. Will probably require some post-processing to sand and melt the bottom edge for a better seal. I recommend sanding the sealing edge at 320 grit until rough texture, passing a torch over it to remelt, and then pressing onto a smooth surface to remold the edges so they seal better.

I printed with TPU 98A 15% infill, no supports.
