It's not pep, but there's a guy that modeled the Cyberman head and uploaded it to one of those "pay what it's worth to you" sites. I printed it out and did all the damage manually for my Handles. I can't remember where the file was, but I found it because a guy started a thread on here where he was making either Handles or a Cyberman costume, which referred back to the CAD forum where the creator posted his WIP Cyberman for himself and his son, and at the end of his build, he linked to the download page. Sorry it's not more precise, but it's been a long time. But hey, the hunt is half the fun, right?
