PCIe Lime SDR to blank bracket adapter

Lime PCIe SDR ships with no PCIe bracket - quite a pain. Further, they're tough to find.

I designed a small interposer that allows a blank panel to be mounted to the card.

Notes:
1) Relationship between bracket and adapter
The bottom surface of the lower gusset is exactly 4" away from the bottom surface of the bracket mounting tab.

2) Have included a DXF file for machining the blank bracket to match the adapter. Cut an inside offset using an 0.0625" cutter.
