Please note: I have achieved better results with this template: http://www.thingiverse.com/thing:968038 although it does not comply with the rules of antenna making...
Template for making perfect bends into 0.8mm copper plated MIG welding wire creating a circular polarized cloverleaf/skew-planar 5.8gHz FPV antenna.
Added a 1.0mm and 1.5mm version. No idea how the antenna is going to perform with thicker wires...
2015-05-27: Added a 0.5 mm version.

Using the guides and calculators from RCExplorer.se: http://rcexplorer.se/diy/2011/08/the-cloverleaf-fpv-antenna/
Produced a tool for a 5800Hz tuned cloverleaf/skew-planar antenna.
The tool helps you to:
Cut a 0.8mm copper plated MIG welding wire to precisely 63mm
Then bend it 90 degrees at 13.2mm/26.5mm/13.2mm/10.1mm
Then bend a perfect loop with an angle of 115 degrees
Do print the tool at 0.1mm layer height, ABS.
