Monoprice Ultimate 40mm blower fan duct

There are a number of different Monoprice Ultimate / Wanhao D6 fan duct replacements out there, but they seem complicated, large, and encumbered the heat sink cooling. This design takes the lightweight design from JGTMaker and makes it blower compatible. Many of the blowers either didn't use all 3 of the original mounting screws, or added structure for custom mounts to keep the ducts from sagging. I tried to keep this as simple, compact, and light as possible.

I have not run any tests yet,
