Raspberry Pi Model B (Old Version) to Model B+ Mounting Adapter Plate

I wanted to mount my old Raspberry Pi model B (version 2, with the screw holes) in an enclosure that only had the mount points for the B+ model. So I whipped up an adapter plate with holes in the plate for the B+ screw holes, and standoffs for the B screw holes.

Screw holes are for M2.5 screws.

I included the 123D Design file, so you can modify it if you need.
