Quick release nut for cymbal

This is quick release for cymbal or something else.
It is made for two metric threads M6 and M8.
The M6 has two identical pieces for the casing.
The M8 has a smaller pin, so the casing is made of two different pieces.
I printed with ABS material and assembled with acetone.
You could also stick with glue.
In the middle there is a small spring that you need to get and insert. In the picture is only marked with a pencil.

On request, I added an option where the housing is screwed with a small countersunk wooden screw with a diameter of 2mm.
