RepRap Pro Ormerod v1 - Simplified X-Carriage (based on dc42's openscad rebuilt x-carriage)I have drilled two additional 3.5mm holes in the heat sink and mounted the fan & heat sink directly onto the new x-carriage with two M3 x 40mm bolts. The aluminium cooling block is mounted onto the heatsink via the two existing holes and M3 x 40mm bolts. I have added a slot to tidy all the cables into and generous clearance for the bowden tubes movements.
