@mediaman problem with duct models.

I had initially printed the dual 5015 duct, but when I went to install it I discovered that even with the stock 40x10 hotend fan, the hotend fan almost completely covers the intake for the left 5015... no use carrying the extra weight of a fan that isn't doing anything, not to mention the uneven part cooling this will cause.

The problem:
After discovering that I printed the single 5015 duct. However, it doesn't fit with the fan on it using the Ender 5 base. The single fan duct is shorter in Y (as installed) than the dual duct is, and this causes the back of the 5015 to interfere with the X-axis belt crimp. See attached pictures of model comparison and how it sits on the machine.
The single fan duct must be lengthened in that direction for it to work at all.
