Customizable 7-segment display module

I needed a small display for my fridge, but couldn't find the perfect one (besides in some places these are damn expensive) and I wondered how a printed seven segment display would work? The answer is that the printed display works very sweet!

As an extra bonus notice in the openscad code that I adapted most of the led sizes based on a logaritmic and quadratic formula (to define the led height and flange size based on the diameter) rather than hard-coding every set of parameters, quite nice eh?
