The whole thing was printed on a Makerbot R2X in ABS, except for the sideplates which were cut out of HDPE on an X-Carve 1000mm CNC Router.

I'll eventually publish the source Fusion 360 files, in the meantime the STLs should be in mm and the printing orientation might be wrong. NOTE; The parts labeled as 'REFERENCE' are for reference only and shouldn't be printed.
