Summary

This is a remix of an existing blast gate concept.

Improved a little for my usage:

Tighter fit for 40mm vacuum pipes (german "HT Rohr"): reduced size by 1.5%
Increased pipe connection length for better stability
Increased radius of slider to better close up air flow.

Doesn't need glue, fits nicely and works great in my little workshop!

Big thanks to the original designer!
