3D printer enclosure light shield

I had couple of old neon light that I have removed from my kitchen (replaced with led). It is classical 7W neon tube about 30 cm long. I have used it as light for my 3D enclosure and I wanted to block light to outside of enclosure.

Because of that I have constructed 2 pard shield, each 16cm long that can be joined together.

Printer Ender 3 Pro, 20 infill, 205 nozzle and 60 bed temperature.
