Micron+ R1 (180mm) side skirt with horizontal keystone

The keystone was rotated to be horizontal to clear space with electronics. 

Note: I use the FT EMS mod for my Micron's electronics bay, so I can't guarantee that that this mod will work perfectly with the default electronics arrangement (however, the CAD suggests it might work).

Extracted the keystone from the rear skirt piece to position it on the side skirt after rotating it 90º to gain clearance with electronics. I've also added a screw-driver hole to the keystone to ensure the original design intention is maintained.
