A little adapter I came up with to maybe make the path the filament travel through the lid more in line. Maybe it will help keep the filament from catching, and keeps the ptfe tubing from pulling out. It uses the nuts and the cap plugs from the stock adapters. 

Updated: Redesigned the adapter to make the threaded shaft bigger due to angle needed made the hole through the center too close to the edge of the threaded shaft. Included the nut files for the larger size threaded shaft. You will have to open up the holes in the drybox to 1/2" (13mm) to use the version 2 adapters, I used a step drill on mine and it worked well (just don't get in a hurry drilling out the holes you could crack the housing if the bit grabs hard). The ptfe connectors I used are: PC4-M10 Pneumatic Quick Connector Fittings, Bowden Tube Coupler Male Straight PTFE Tube, and can be found on Amazon.

The version 2 adapters seem to work well. I left the version 1 files up in case you want to try them.
