Um, no I didn't actually. Not sure where you got that idea - I create all of my own 3D models - but I do accept commissions
My version of Radec is postponed at the moment. The Radec helmet isn't being designed as a pep instead it's going to be broken up into parts to be milled on my CNC and house electronics. A pep version may follow at a later date.
Another member did however make a great HD Radec helmet pep file that he had up for sell - I think it was Ironiumcostuming. If that wasn't him I'm really sorry it's been a while.
You also have Rundown's model which was one of if not the first out there, including the chest. But nobody that I know of is giving those files away for free, sorry.
