After accidentally homing while there were still printed parts on the bed the original broke.
All step files are available on Github. This just adds a small extrusion to the bottom to make for a flat bottom.
V2 also adds a piece on the side to keep the fan from sagging and eventually hitting objects while printing. I have had problems with this in an enclosure.
I printed it with supports. If using Orca Slicer, support style may need to be set to Default (Grid/Organic) for the front to be properly supported.
The screw holes might need some slight reaming with a something like a Torx screwdriver to get the screws to take.
The original is known as air deflector2 in Frame 3d printer pre-assembled.zip on github.
The author remixed this model.
