50mm Fan for Venom T45 EDF

Update - Please use 7Blade.stl - It's a greatly improved design, which provides greater thrust and efficiency. In fact, it provides greater thrust than the original fan that came with this jet.

Designed as a replacement fan for my Venom T45 50mm EDF Jet. I broke the stock one, and couldn't find a direct replacement, so decided to make my own. Should fit any 3mm threaded shaft with nut.

Static thrust is almost as much as the stock fan (maybe 85%) and is tested up to around 50k rpm without failure. I have yet to actually fly it as of uploading, but I feel like it should work okay. I expect the efficiency is not as good as the stock part either.

Please test before you fly, and use safety goggles! Spinning anything up to high RPMs can be dangerous, especially 3D printed parts. Use with caution!
