Ultimaker Fan Shroud for DualHead

- based on the new UM2 fan shroud design
- ALUMINIUM sheet metal bend housing
- to be used with 2pc. 25x25mm fans each side
- modelled for dual printhead design => BOTH AT FRONT SIDE!!!!

WILL NOT FIT TO OFFICIAL Ultimaker DUAL EXTRUSION UPGRADE !!!
Big advantage: you can close the sides of the UM with acrylic glasses without having to consider the fan duct space !!

Note: not tested up to now
