dust collector for the Lewenstein 700de overlock

This “Thing” is useful as dust collector for the Lewenstein 700de overlock machine. My wife found it effective!

Version 3 has a small tab on the side that holds the dust collector from sliding towards the machine operator.
In addition to a Velcro on the other side it’s an improvement one can consider.

I tweaked some other sizes. They are orange colored in the 3D picture.

Version 2 remains available for it remains a good simple option as well.
