CR10 heatsink fan duct/shroud/support

cults3d

Update V2 (23/05/18): I have added some space for the fan screws, since V1 had some air flowing towards the bed instead of the heatsink - see picture from below. Now all airflow is going in the right direction! .......... I quite liked the appearance of the extruder part of the CR10 - looks very professional. However, the heatsink cooling is not efficient at all (when too much retraction on slower printing speed, it blocks the nozzle giving under-extrusion). This is a simple mod to add inside the stock extrusion cover to allow for better flow towards the heatsink - no support plate, no screw, no nothing. Just snap it in, and you are ready to print!
