Sunlu S2 FIlament Dryer Port Guide

I was frustrated with the difficulty of feeding the filament end through the port in the lid of the Sunlu S2 filament driver. The location of ym dryer makes it difficult to pick up so I wanted an easy way of finding the little port hole without looking. 

This is my first ground-up Fusion360 model, but I think it turned out really well and it works just as I expected. So much easier to "find the hole" and the filament just slips right through now. Print 2 for the two ports in the lid, they only fit in one way and the little clear tube pieces remains, fitting in the counterbored hole on the back. The edges print so thinly you are bound to get a bit of imperfection (wabi-sabi) but it does not interfere with function at all.

I printed in basic Sunlu PLA 0.1mm layer height with a 0.4 nozzle to make the interior as smooth a possible and printed on its side seems to produce the best results and the cleanest counterbore. YMMV. if there are source files I can provide just ask, otherwise i've given the 3mf and the stl below.  If the model has some weird bumps when you zoom in, it's only because I traced a photo I took of a positive mold of the cavity and i'm still learning F360. maybe you can do better?! let me know!
