T bottom

This is a replacement part for the acrylic T-bottom for [CowTech Ciclop 3D Scanner](http://www.thingiverse.com/thing:1335535)

So the bottom piece of the T bar broke for me so I made a new one from the dxf file used to laser cut it originally.

The slits at the end is supposed to take a small nut but they are to tight so I had to use a file to make some extra room. If you want to avoid that I suggest to modify this some more but I did not want to print another one and I do not want to upload
