DN40 Gate

Made a DN40 gate to be able to close seperate outlets of my vacuum which is integrated under my wokbench.
It can be used with an original DN40 sealing.

The parts DN40_flange and slider_holder have to be glued together

I made the slider_holder a little bit higher than the slider itself. Depending on the accuracy of your printer you have to sand down the height of the slider_holder a little bit to get a perfect fit for the slider.
