Having recently picked up UW-EX Baldigus, and seeing those figures along side the rest of my RID01 collection, I've realised I'd love to have a copy of the six original Spychangers from the show, but in an updated form, much like the Unite Warriors version of Baldigus accomplishes. As such, I'm planning to customise some Combiner Wars figures to match, but would need to create new heads and possibly weapons for each character. So my question for modellers and designers alike who print and fabricate in personal set-ups or using a service like Shapeways, what software do you use for your designs? What would you recommend in regards to learning curve, ease of use and functionality? Cheers!
