The new Maze 3 brought this design back to mind that I had laying around. The design itself was thought up by webmedic and I told him i would try to make one. I got the drawing made but when I went to run it through the CAM software the code was all messed up. I ran out of time to work on it so I gave up.
But anyway what do you think. The channel is huge. It would have a high volume of water going through it. It was made for 1/2" ID barbs.
