Gave this a boost, as I've been looking for a project like this myself and really liked the way you documented everything in the README. Wishing you a happy new year and sending my thanks for publishing this! ~n

@andrey Yes, the .stl and .scad files are in the repository too. It's a pretty rudimentary case, but should work, if the sensor can be placed out of the way somewhere. (Pull requests by more design-savvy folks welcome!)
