I'm using Polymaker's Polydryer for drying and storage of TPU filament.
I was looking for a solution that keeps Polydryer's perfect seal in storage while minimizing the fuss between storage and use of the filament.
Since I'm using the PTFE tube that comes with the Polydryer for feeding the filament to the printer, this means plugging up that tube after unloading. The existing solution that comes closest is https://makerworld.com/en/models/1064668 . I particularly like the retaining strap, but the idea of stowing the end of the filament into the cap seems unnecessarily fussy to me.
Instead, this model allows plugging the end of the tube with one hand, while the other hand bends a comfortable portion of the filament over the tube's rim. Thus, the filament itself is part of the plug and a small portion of it is not dried, but that part is likely only purged anyway!
I used https://www.prusa3d.com/product/forward-am-ultrafuse-tpu-95a-black-750g/ with the default settings in Prusa Slicer.
