About this 3D model

In building my CNC machine, I ran out of those nice metal 8mm shaft supports and I just didn't feel like ordering more and waiting on them, so I designed this and off to my Solidoodle I went. I also have a 608zz bearing support and a block I used to mount my mini-CNC machine's X-Y table in which I put my threaded rod, in case anyone is interested in that. If so, leave me a comment here.
