3D printing - Veroboard Base

I've been using the UP! 3D printer for 2 weeks now and one of the common problems I've had along with other is warping of the corners for large prints. People have been using the paint, blue painters tape, kapton tape and other such ideas. I've tried the paint and blue 3M tape with mixed results and been a bit annoyed with the high maintainence.
It was then we stumbled across a really simple solution - veroboard. Veroboard is basically a PCB with lots of regularly placed holes. When you print the bottom layer goes into some of these holes and sets - keeping the model firmly anchored to the base.
