Loving the dry box with tubes. I'm assuming you haven't detected any extra drag from that setup?

I did when I was using 2mm ID 4mm OD ptfe tube, however when switching to the 3mm ID 4mm OD ptfe tube linked in the details the resistance/drag went away

furthermore I've been printing on this setup for a few months now and havn't had a single jam/clog etc related to filament frictiion in the tube,

ptfe is a lubricant as a product so it really makes a terrific product as a tube, especially if you plan it so there aren't any major kinks or bends

I've got a few shallow curves in the tubes but with the 3mm interior dimensions the 1.75mm filament has no problems and pulls smoothly even though my design has something like 3-4 feet of tubing it has to go through

originally I planned on adding a filament oiler / filter but it hasn't shown to be needed as everything is working great
