RepRap Ormerod 2 quick-set dual-nozzle dc42 sensor board PLA/ABS switchable heat sink enclosure and nozzle-cooling ducts

This was migrated from my Thingiverse profile and is from 2016.

Hot end heat sink enclosure and ducts for Ormerod 2 quick-set dual-nozzle setup with dc42's improved differential infrared height sensor board.

A removable shutter allows airflow to be directed at the nozzles (for PLA) or upward (for ABS). Or both at a reduced rate (shutter removed completely).

You will need to rotate the heatsink 90 degrees so the fins are vertical. A third hole will need to be drilled into the heatsink to allow for the bolts. You will also need to widen the holes for dc42's sensor board (I used a 2 mm drill) and possibly those for the fan bolts (I used a 3.5 mm drill).

This design is completely parametrised (and I mean completely, everything from dimensions, to number, offsets and symmetry [or lack of it] of top and bottom vents, ducts, and duct geometry) so I should be able to change a few numbers to generate versions for the old-style one-piece nozzle or single-nozzle hot ends. I'll post them on Thingiverse in the near future.
