If you're like me, you're tired of wrenching the lids of these Polydryer dryboxes open every time you need to load filament. I leave the PTFE tube in the dryboxes even when I don't print, so that I don't need to open the box to load my printer with filament. However, I noticed that the moisture in the dryboxes goes up significantly faster when I do this, since the gasket does not create an airtight seal around the PTFE tube and leaves holes open.
I solved this by creating a simple ring that slides into your PTFE tube and plugs the holes, creating an airtight seal. I've done some experiments, and at 60% RH, my dryboxes with this seal hovers at ~10%, but the drybox without it stays at ~20%.
