About this 3D model

This is my attempt to design an x carriage for the reprap discount bulldog xl to try an reclaim some print area for the i3. The bulldog is an excellent dd system, however is heavy. This is my attempt to rotate it 90 to prevent the canterlevering effect hat results in x-carriage failures. Bringing the weignt closet to the rails should also mean less vibration and increased printing speed.s
