Banana Pi clip Case

This case is designed to be laser cut from 3mm acrylic.
The tolerances are very close but the design has been successfully
realised, though even the protective plastic covering upsets the slot
sizes enough to cause issues.
Using 1/8th inch acrylic does not work with this design!
I used 10mm long M3 nylon bolts to hold the board to the base with
nylon washers underneath the board as spacers.
Layer 0 (black) is the through sheet profile cut.
Layer 1 (red) is the connector and slot
