Simplest Drybox Passthrough you ever seen :D

thingiverse

I've put together a dry box for my filament from multiple versions. When I printed from the box, I discovered that the passthrough designs I found on Thingiverse were not suitable for my needs and often required extra effort. My box is positioned on an Ikea cabinet, and the filament flows directly down from the box into the cabinet. However, the material in the feed consistently becomes bent to such a degree that the filament clamps and fails to roll off cleanly. To address this issue, I decided to find a solution. Therefore, I printed a TPU guide for my 16mm holes in the box. I believe this is the easiest and most effective solution so far. The filament is rolled downward at an angle and led out of the box into the cabinet at a 40-degree angle. It runs very smoothly and doesn't jam anywhere. To replicate this setup, you'll need a piece of PTFE tubing with an outer diameter of 6mm to guide the filament out of the box. Have fun with it.
