CR10 heatsink fan duct/shroud/support
thingiverse
I have updated V2 of this design with some extra space for fan screws, since V1 had a flow of air going towards the bed instead of the heatsink - see picture below. Now all airflow is flowing in the right direction! The extruder part of my CR10 looks very professional, but the heatsink cooling is not working efficiently at all (when too much retraction on slower printing speed, it blocks the nozzle giving under-extrusion). This simple mod adds to the stock extrusion cover inside 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!
