I believe you might be half right. While I did follow the measurements given by FIRST, now that I look at it, the plastic on the vision tetra is a little thinner then it should be. That's easy enough to fix.

Since I based these off of Petek's model, I'd be happy to share them with anyone who wants them. I don't have a place to store the files at the moment, but can email anyone who PM's me with a request for either the max or inventor files.
