A addon for the Sunlu S2 filament dryer.

A clip to open the box a little bit so that the humid air can leave the drying box more easily.

This clip opens the box 5mm and has a hole for extra ventilation.

In my other uploads you can find a 10mm and 15mm variant with a larger hole in it to increase the ventilation even more.

Or the 5mm clip without hole to have a little less ventilation but keeping the heat as much as possible inside.

These are the links to the other models:
