Ben's files aren't as polished or as accurate to screen used than Paul's, but they're much better than Sean's which were designed so long ago now and there's been a lot of detail discovered since then. There's a good number of "upgraded" parts on Thingiverse for Sean's, but it becomes a duck hunt finding it all. 👍
Same for Sean's E-22, it's not worth printing now that Helvio's is freely available
