I printed the original nut and screw out of PETG since it is a structural part. All the cap is doing is sealing off the hole, so I made it out of PLA and it works great.
The original cap-nut "Cap for Screwless Filament Feeder - 1.75 - Dry Box by TB123456789" does not fit for some reason. So I took the nut from the "Screwless Filament Feeder - 1.75 - Dry Box by DarthxRinzler", flipped it upside down, and then added on to the top of it to create a channel for the PTFE tube and filament to protrude through a little. Works great now!
