Holder for chip bowl

I don't like chips on the floor when I tinker at a small desk in my bureau. Up to now, chips from sawing or filing fell to the floor. Now I have a turnable bowl underneath the desk which can be swung under the desk ülate when not needed.

You will need a M8x60 hex screw, a washer and a securing M8 nut as an axle. The ring fits over and under the lower part which makes it possible to place the bowl higher or deeper.
