Adventurer3 simplified fan duct & dual fan duct

cults3d

I simplified the official fan duct upgrade data for FlashForge. http://flashforge.co.jp/support/#down When generating supports on FlashPrint, make sure to enable "Touch platform only" option. I also designed a "dual fan duct" inspired by martin_au's "Dual fan duct for FlashForge Adventurer 3". However, my duct has no visible effect on printing quality. 日本語公式サイトの「Adventurer3ヘッド部分ターボファンダクトのアップグレード部品」のデータを元に、プリント・取り付けがしやすいよう改変しました。 I removed the rear half of the original design since it seemed unnecessary. I doubled the thickness of the plate to make it less prone to breaking. I added a handle for easier installation. Please check "Touch platform only" in Supports Options when generating supports, and you'll avoid creating supports inside the duct. I also uploaded an extra "dual fan duct" model based on martin_au's design from Thingiverse. However, my model did not show any difference in performance compared to a single fan duct.
