UPDATE: Added to the fun. Included Mordiev's cap to the front piece. Print with TPU and it works great!
I love Antipode's knurled pass through for PC4-M10, and also love kenny93's filament funnel, and then realized the two would work well together. The funnel has a lip that stops the PTFE from encroaching into the container.
The funnel makes feeding from inside the drybox that much easier. I printed the inner piece in a bright yellow to contrast well with most filaments, while the outside is black.
I printed 0.20mm layers, no supports.
