Z axis bearing holder

I recently bought this 3D printer and it worked great. Everything was working right except the Z axis bearings kept vibrating out of their sockets. I was going to glue them down, but then I remembered, I have a 3D printer. So instead I designed and printed this model. I have only included a file for one side, so if you want one for the other side you will have to mirror it. Other than that it works great!
