This guy Les put together a piece of software to view/calibrate a spectrum[0]. He also has a YT channel[1] where he builds a couple RasPi spectrometers using pre-made spectroscopes that run $50-100, but the whole package is a lot more compact.

There are also a number of spectroscope enclosures on thingiverse, but it's always so hard to gauge if any of the projects are actually worth printing. The most dead-simple and cheap example I found used the same slit/CD plastic combo capped onto the ends of a paper towel tube.

Some other stuff[2,3,4]
