I hope you sell millions of these. It is such a simple but elegant solution . For whatever reason, I completely dig not having switches visible on the playfield.

To be clear about "simple" since that could be interpreted wrong ... what I mean is that you're not using a bunch of complex stuff. For example, they used a processor with an inductor on Alien for solid state switches. I always thought that was slick, but overkill since TI has had a single chip solution for that available for almost a decade now.

Your solution cuts all of that crap out of the equation and replaces it with some common, passive parts and a 3D printed mount. Plus I believe you gave away a few examples on Thingiverse .

Like I said, I hope you sell millions . I completely dig endeavors like your's and need to stop overthinking when it comes to solutions to problems .

You could probably use an SLA 3D printer to print the MRS housing for star rollovers using a translucent resin to address lighting issues. Translucent FDM prints are not as clear though they might be interesting looking when lit.
