For large images:
This is a nixie tube. I've labeled everything very clearly and the only texture I used that wasn't procedural was the HDRI environment texture. You really need one of these if you are going to see this in all its glory. Had a little trouble with beveling the numbers. For some odd reason they took on random thicknesses but all within tolerance. The p3d doesn't show any of the materials correctly so I chose to render it as mesh in that. Looks pretty crappy.
