Re: [neonixie-l] Colon light pipe

It might also be possible to use ordinary LED light guides. A thin tube, 
metal or plastic, where you just drill holes for short LED light guides 
will probably work too.

Tektronix, and other instrument makers, used light guides for NE2 Neon 
indicators with either short light guides (sometimes without too) and in 
some cases long twisting light guides for indication on the front panel.

 Here's a 3D printed colon light pipe design for anybody that's 
 interested.  A standard T2 neon lamp sits inside the pipe.

 The pipe is 3D printed with clear material.  A scrap piece of tubing is 
 used as a mask to block light transmission except for the colon dots.

 The stl file is attached.

What kind of material is it ? I've only used PLA, trouble-free for many 
years now, because others I know have had all sorts of problems with other 
materials.
