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.
