I came up with a plan to build one of Andrew McNeil's antennas using CNC precision and thicker material than a PCB. I asked him what thickness he would recommend, and he replied that 1.5mm would be perfect. You can find his work here: Instructables site http://www.instructables.com/member/andrew%20mcneil/, Youtube Channel https://www.youtube.com/user/8bitandrewmcneil/, Shop http://andrew-mcneil.com/, and Patreon https://www.patreon.com/user?u=2476215. I used his plans to create a design that would have a 3D printed support structure and CNC machined elements, and this is the result. I'm not entirely sure if it works or if there's an assembly error. I ended up heating the elements and press-fitting them because my 3D printer isn't precise enough for aligning the elements. I used 5mm threaded rods to bolt all the plastic parts to the reflector, which might affect the signal but I'm not sure. I also think that the rounding on the inside of the elements might not be ideal. To print this, you'll need to make seven or eight pieces of 02-Spacer.stl and one of everything else. Eight if you don't print the part for the mount.
