VERTEX K8400 - adding extra 10mm along Z-axis

While upgrading my K8400 printer with MK3 heatbed, I realized that adding the bed and cork isolation under it will "cost" me few millimeters along Z-axis, so I started looking into options of regaining this space. As the result I designed new lowered mounts for aluminium plate, which I am posting here. If you are not planing to add heatbed, you can still use these mounts and get extra print volume.

Here is what you will need to do:
1) Print 2 copies of bed_mount.stl and one bed_mount_center.
