I designed this part to bring my part cooling fans closer to the hotend so I could make an enclosure. There is no need to buy any more screws because this uses the screws from the injection molded shrouds.
I used MatterControl to slice this object and the supports came off easily with no hassle. I did not have my retraction settings dialed in so my parts are a little crappier.
I originally had the height shorter but due to the plug for the whip was too tall I had to raise the height and pull the wire through the intake triangle for the shrouds. I made two service holes for a long screw driver to fit down to screw the shroud piece to the cover holes for the PCB. I am currently looking for some sort of plug to keep air from exiting these holes to provide more air flow to the parts on the bed.
