A still air box (SAB) is used by hobby mycologists all around the world. With it, the inside air doesn't move, which results in that all pollutions sink to the bottom and don't contaminate the media you work with.

This is done with a IKEA plastic box, where you cut out holes for your arms. This ususally leaves a big gap between the edge and your arm, where outside air can still flow in.

I saw this as a problem and printed out some covers with TPU, which seal the gap.

The size of it is 16 cm, so the hole should have a diameter of around 12-14 cm.
