Geeetech i3C dual extruder shroud for 2x 50mm radial fan blower+ 1x 40mm axial fan

==== (update 09.01.2018) ====================================
today i was able to finalize my latest BLTouch mount, wich is a perfect add-on to this print:

BLTouch Auto-Level - adjustable, back-mounted ( Geeetech Prusa i3 B+C Dual )

=========================================================

3d printing is all about trial and error.
that being said i never found a good Part Cooling Fan for my Geeetech i3C dual extruder. so i took a few well designed models and remixed them together (check out the sources below).

after some testing, i came up with this model.
well, it aint pretty but gets the job done!

BE WARNED:
i modified my printer head. i crafted a thinner aluminium bridge (the silver part your two extruder stepper motors are mounted on). the old bridge had 10mm and my new one got rid of those two feet and is only 5mm thick. that way, my nozzles got below the black plate behind my printer head, so i can use the whole printing plate instead of rushing into the clamps.
that being said, it could be possible, that my model is too low for your untouched printer head. if so, please contact me...
