E3D Bowden Makerbot Replicator 2X Conversion Bracket

I haven't been using my Replicator 2X for a while now, mainly because it doesn't extrude well...or at all most times. I decided to swap over to a Bowden style extruder.

I originally followed the [guide here](https://www.matterhackers.com/articles/hack-your-makerbot-with-an-e3d-all-metal-hotend). The guide gave [a link to some 3d printed parts](http://www.matterhackers.com/store/digital-designs/makerbot-e3d-hotend-swap-kit), they were all undersize for me and I didn't like the way the hot end was being secured...so I made my own.

Note: I never really use the dual extruder setup, so this bracket only supports one extruder.
