That is really cool stuff!Maybe one day it is possible/affordable to use a 3D printer to print these cathodes and grids using a conductive plastic of some sort. As it is all low current, it may not need to have very low resistance. And then of course, if you had 2 types of material in your printer

Not much to it - it's like etching a printed circuit board. Coat with resist,
expose to pattern, develop, etch.
Places like Micro-Mark sell kits to do this:

I agree with threeneurons that cuts down to that distance apart are
going to be iffy.
I know that there are companies that laser cut solder stencils with
machines like I have, though, they might be using a different laser head
than the one I cut with.
So, Dalibor, I'll contact you offline with m

I use to work closely with the laser people. Use to cut stainless (316 &
304) down to around 0.010" (0,25mm). Should be able to do 0,1mm thick, but
cuts 0,4mm (0.016") apart, is going to be iffy.

Im not sure, but i think you might be able to make the grid from multiple
horizontal wires that would be spot-welded together. Something like the
ZM1175 or ZM1210 have. It really depends oh how well you could weld
multiple wirest at once.

I had been planning to photoetch mine, but a laser cutter should be
One more thing - I would also provide the layout,

Hi Michael,
the numbers for nixi tubes is one of the problem I havent sufficiently
solved yet. Are your laser cutters able to produce numbers that have 0.4mm
wide lines? The material would be 0.1mm thick stainless steel sheet (316L).
I could send You some sheets to give it a try, just send me you
I visited that museum some years ago. It was fabulous! My takeaways were the
(fully) analogue computer and early memory units using storage CRT
technology... among other inspirational displays.
I can't wait to go again...
