Nixie Tube Clock Frame

I recently received and assembled a [Nixie Clock Kit](https://www.tindie.com/products/RobG/msp430-nixie-clock-kit/) (not my kit) for my birthday. However, there's a 180V no-touch area. With 2 kids, I wanted to build in a little extra safety to keep fingers from wandering into the danger zone. It also helps to block out stray light since I use it as a bedside clock. If you use ABS and polish it, it also reflects a little bit of light inside the clock that gives it a cool effect. Black works
