Here is a model designed to remove air from a "cereal box" / Airtight Cereal Storage Containers.

This model is inspired by others I have seen here and there.

I use it mainly for my Coffee beans but you can use it for and dry Storage.

You just have ou just need to draw (outward) the air through the one-way valve

Printed with Transparent PETG but you can use the filament of your choice.

To ensure that the valve is screwed in properly without damaging the threading, it is advisable to deburr thoroughly using a deburring tool.

You need to Buy the following:
