I am about to build the ZenXY V2, but I cannot seem to find where the pipe sizes are listed. It says there is a larger and smaller OD pipe required, but does not specify the actual dimensions. Maybe I am completely missing it, but if someone could point me in the right direction that would be great!
They are EMT tubing, the smaller is 1/2" and the larger is 3/4". Those are standardish sizes in the US and measured on the inside diameter. The outside diameter of the 3/4" is 23.5mm or so.
