BF-99 Cube

While masochists with too much time on their hands could conceivably put a reasonable U-coil build into that, it's more of a horizontal-coil RDTA that would be much better suited to cotton/rayon through the coil. (Mesh wick tubes into the tank would be great, though.) And since U-coils really suck if you're not rolling the mesh on the bias, especially if you have to make a hard transition from vertical to horizontal in a small chamber with a low ceiling, you'd need to source larger sheets or rolls elsewhere (EBay, Amazon, local yacht chandler, etc.) - nothing here will let you get a large enough piece when you orient the wires at 45 degrees.
