Hackaday reports

Digging though a carpet or dirty shop floor [for a dropped part] usually results in frustration.

[...]The idea here is to suck up and contain the part without having it making [its] way into the vacuum. To do this there would have to be an intermediate chamber. For this, [Frank] used a multi-pack CD container. This was a great choice because it is clear, allowing him to see what enters the container, and it unscrews quickly making it easy to retrieve the tiny part.

The inlet and outlet connectors are made from PVC and are attached to the CD container's base with adhesive. To keep the debris from getting past the CD container, an old kitchen strainer was cut up and the screen material was used to only let air pass.
