NEW VERSION: Push-Fit Tube Holders For 6mm Outer Diameter Tubing and Anti-Seizing Filament Guide for Filament in Individual-Spool Dry Boxes

These pieces are designed to be used with my individual-spool drybox inserts. The outer fitment is a panel mounted push-fit holder for 6mm outer diameter tubing, and the inside fitment is a funnel guide for filament being pulled from spools that are almost out of filament.
