Smoothed Drybox Passthrough

This is a bit of a mashup between the two linked fittings. both designs are beautiful and I don't think I did them any favors from an elegance standpoint but I do believe I've made them slightly more functional at least for my use case.

- I adapted the funnel design from Subsite so it would fit with Bipsen's adapter.

- I then added some additional material to the inside of Bipsen's pass-through so that the filament would no longer catch on the backside of the installed fitting.

This is my first remix I've posted, so if anyone has any comments on how to improve it's presentation or on the files themselves please let me know.
