These are fittings for the PTFE tubes running from your dry box to your printer. The PTFE Retainer is a snug bead which holds the tube and prevents it from sliding in or out of whatever you're using to pass through the wall if your dry box. I use one inside and one outside, butted tight against the sides of the dry box to keep the tube in place. The PTFE end cap is a press-fit closure for the end of a PTFE tube that isn't in use. I use it inside the box if that PTFE tube is empty and at the end of the tube outside the box if I have filament loaded in that tube, but it's not in use with the printer. These are very non-essential, but now I don't have to wonder if the PTFE tube is slipping out or stray moisture is creeping in -- or fouling a filament sitting in the tube for later use. I had to do a lot of scaling and testing to get these to fit correctly. The end cap should press into place pretty easily, but still be snug on the end of the tube. Not falling off, but something easy to remove or replace. The PTFE tube retainers should be pretty tight. I want these to keep the PTFE securely in place in my dry box even if I accidentally pull on the tube, snag it against something, or otherwise apply moderate force. I made a test print of a handful of each part, scaling up in 2% increments, until I found the fit I liked for each. I then printed a full set -- 1 cap per tube, 2 retainers. I did not design the screw bulkhead fittings that seal the side of the dry box where the tube passes through. That's [Screwless Filament Feeder - 1.75 - Dry Box](https://www.thingiverse.com/thing:1750875) by [DarthxRinzler](https://www.thingiverse.com/DarthxRinzler). It was exactly what I needed for the job and went together easily. The tube was a little loose, though, so I made the retainers to hold on tightly.
