Routing the GPIO cable

I decided I would cut my white case at the top side, so I would have a place to route the GPIO cable outside the case.

Reference line. Dont go quite as close to the edge.

Thick cutting disc (dremel style grinder)

We are done

Cleaning up with an knife

That'll work

Sliding it in from the left, testing to make sure it fits

Excellent!

Could have cut a little less on the right side

That'll be perfect for one of my two demo boards.
