Removed the blade guard from the model for less air resistance, adjusted the thickness of the duct a tiny bit to avoid crashing and belt rubbing.

You can use the stock phillips screws for the faceplate or you can use these M3 x 14MM screws

Made a version that uses M3 heat set inserts and M3 X 5MM screws (The longer M3 screws will also fit)

I do not recommend using this version if you are going to use the stock exhaust fan as it has potential to hit the belts. I have an auxiliary fume extractor on my printer and have my stock exhaust fan removed.
