While the PCBs looked nice, they didn't quite have the contrast to read them in daylight. The filaments chosen were delicate too; remember, they're made with ceramics! A case was in order, and I wanted it to fit some of the design features I saw in minitrons, like a product number being debossed into the case's side. Using Fusion 360, I made a simple case that the PCB inside and is secured using M2 screws tightened to het set inserts. I added some blocking inside to better focus the glow of each filament segment too.
