About this 3D model

This is a model of the QUBD silicon Heated bed, 225mm x 255mm version: http://store.quintessentialuniversalbuildingdevice.com/product.php?id_product=30 I needed this model when designing my machine, but QUBD would not answer my emails about the width of the protuberance where the wire comes in. I plan to use thermal heat tape to build up the shape on the bottom to level out that protuberance. I figured now that I have it, I measured it for my model, and I'll share it in case others need it.
