Look up the Dollo 3D printer. All the files are free to download. It
includes pieces of herringbone rack and matching gears. Could have some
examples printed then make molds and cast in high strength resin. Could
also use the 3D files to 3D mill steel racks and gears.

For my future project (cnc router) I will have to use helical rack and

It ocurred to me a while ago that if using a double-helical rack and
pinion then you can achieve zero backlash with an axial displacement
of the pinion/gear relative to the rack.
I don't know if anyone has ever done that.
