Printed Z axis brace for PrintrBot Plus v1 1303

The laser cut holders for the Z axis rods on the v1 PrintrBot Plus were wobbly so I made some 3D printable holders instead. It is a very tight fit by design and the rods need to be hammered into the blocks. It makes for a very stable Z axis. The two files aren't identical. The left and right sides are very slightly different.
