Poly/subd modelling study in Blender of a compact cassette.
Some of the vertices could probably have benefitted from a cleanup and smoothing, though given that this is mostly flat, it's no big deal. Something like this would likely have been better suited for parametric or boolean-based hard surface modelling, but I did do this to specifically practise poly-subd.

Now they exist only as digital ghosts, like this one.
(...except that's not actually true. I still have mine.)
