Revo Hemera XS MGN9 With Beacon3d Scanner

I'm designing a large printer and wanted to use a Hemera XS extruder.  I found this model by 
Bjørn A. Andersen and modified it to fit my setup which is a 2020 rail with a MGN9 linear rail on the top and bottom for the extruder to slide on.  I also re-designed the air duct to have 2 outputs and to add a mount for a Beacon3d bed scanner that I plan on using. I figure that it could help others designing something similar.  The original model was for a RatRig printer, CoreXY, I think, if that matters to anyone.  I changed it to work with regular cartesian, the belt stretcher is inline now instead of staggered.

If you find anything wrong or that needs modified, let me know and I'll do what I can.
