Extruder Cooler for Solidoodle and E3D V6 extruder

Parametric design, so it should be easy enough to adjust for any extruder configuration. Requires a 30mm x 7mm fan, 2 x M3 x 25mm screws for attaching to the carriage, and 2 x M3 x 15mm screws for attaching the fan to the duct. Fits onto the "Solidoodle replacement carriages" by Lawsy:

Is tuned to work with an E3D V6. The extruder mount I've used is the "v6 E3D MK6 Body for Solidoodle" by AZERATE:
