The original hole in the back cover for 4015 fan was enlarged for 6025 fan. As reference the bottom and left corner (looking from back to front) was of 4015 fan was kept - i.e. the hole was enlarged up and right.
Fan duct is attached directly to the fan mounting holes - there is approx 1mm overlap of the duct and the driver heat sinks. X axis driver is colled a little bit better than the Y one due to the low pressure pocket in flow caused by the center rib - I am going to improve it soon.

IMPORTANT NOTES:
1. Orient the duct in such way, the bigger half of the duct is aiming the XY drivers - NOT the opposite way - the duct then not aiming on heat sink at all.
2. Use heat rezistant material - ABS, , ASA, PC, PC blend or ideally fire retardant PC/ABS blend.
