Replicator 1 arcrylic hood supports

I created these parts to support the [acrylic hood](http://www.thingiverse.com/thing:23386) of my old replicator 1.

The first set of parts (left & right) is used to keep the hood from bending backward when the extruder move in the y-axis (and make quite a noisy sound).

The second set (upper & lower) is to support the roof (upper & front facing acrylic plates) from bending down due to the lack of support in the design.

####Note:
These parts may not fit the printer & hood if your print
