Spring-loaded Replicator 1 Drive Block - Modified Lever

Derivation of the "Spring-loaded Replicator 2 Drive Block" by Makerbot

Modified the MBE Lever to use a M3 x 8mm screw to hold the 623ZZ bearing. This was done because I had an issue printing the bearing bolt stub, either being too weak to hold the bearing or over-sized and unable to push-fit the bearing in.

This is the main extruder used for my RepRap 3DPrinter, 3DPrintMi http://www.thingiverse.com/thing:95339
