Cloners might have their work cut out with this one
Without the straws, its relativly simple to make, probably even more so that the WW. I mean, I've got one with simple holes in the spray plate, so has Volenti, and Jaydee I think as well as a few others.
Those straws make it a LOT harder though, I'd never like to say impossible without a cnc machine, but tough, very tough.
Excellent design, very nice indeed.
