TPU Cap for Screwless Filament Feeder

thingiverse

I'd like to thank Sreisig1 for creating the Screwless Filament Feeder, out of all the drybox ports I've found his is by far the most simple and compact. https://www.thingiverse.com/thing:1750875 This part is designed to be printed in a flexible filament like TPU, I'm not sure if it will even work with rigid filament because I never tried. While building my drybox I discovered that I had a mix of spool widths, so to accommodate the maximum variety of spools in my drybox I decided to add 9 ports to the side of my box. The problem I immediately faced was I didn't have nine narrow spools to put in the box and now I had openings that allowed humidity in. So I sat down and built this part, when printed in TPU it fits snugly over the hex head of the port and sits completely flush with the box. The center post actually gets larger at the base to help ensure a tight fit. I have also attached the SketchUp file in case anyone needs to modify it or make something else completely awesome from it. The other cap you see in the picture attached to the PTFE tube was made by Lichtzeichenanlage and you can find it here: https://www.thingiverse.com/thing:2459359
