I am building a 30k btu cascade these days for a friend. I asked eleven to make a special edition for this project.
It is bigger than the previous. 50mm diameter. Capilary tube or cpev in the middle and of course a really long channel ;)
When i will solder it i'll show some more photos.

Special thanks to 11 for the support :)
