TPU seals for Eibos Polyphemus

This is a set of models that can be printed in TPU to improve the airtightness of the Eibos Polyphemus. I don't have a measure for how well they work, but they might help a bit. Keep in mind that this does in now way prevent moisture from entering through the bottom fan inlet, which might very well be the dominant channel of air exchange. I'm still working on a good solution for the bottom fan inlet that still allows for easy switching from active to passive mode, but this is what I have for now:

1) Top plug
This improves the air-tightness of the air outlet valve on the top of the box. It works by screwing into the outlet and so that a seal can be pressed against the box. This works very well and should give a solid seal. This piece is designed to be printed with 100% infill. Remember to remove this plug when you actively dry your filament!

2) Front and back filament plugs
The close any unused front and back filament outlets. They should be printed with two bottom shell layers, two top shell layers and 0% infill in order to become sufficiently flexible. I think they give a very solid seal.

3) Box edge seal
This seal is supposed to go around the rim of the box and improve the seal there. While I really like the other seals, I'm not so sure this is a good design. Take it as a work in progress. I suspect that it might rub against the rollers, and I'm not sure how much more airtight it is. But, I've designed it, so feel free to give it a try if you find it useful. To make this soft enough to be useful, it should be printed with 2 bottom shell layers, 1 top shell layer, 1 wall, and 0% infil. This makes the bottom solid, but the inner wall hollow show it can conform to the lid. It was too big to print on my machine, so it's designed to be printed in two identical halfs to be glued together. I've included two connector strips to help glue the parts together.

4) Top plug handle
The top plug can be a little difficult to screw in because of the smooth sides. I didnt' want to accidentally stiffen it by adding ribs, so I instead designed this handle that can be glues to the smooth top. It should be printed in something stiffer than TPU so you can use it as a rigid handle. I didn't print this myself, but I figured I might as well provide it here anyways. 

Take all of these parts as a work in progress. I would appreciate any feedback and suggestions for improvement.
