The R|Z568M is a massive modern Nixie tube produced by Dalibor Farný and his company. Each tube is manufactured by hand in the Czech Republic. As the name suggests, its design is meant to be reminiscent of the Z568M, the largest Nixie tube produced in the GDR. A picture below shows a comparison between the R|Z568M, an original Z568M, and a Z566M. Despite being the smallest of the three, the Z566M, with its 30mm digit height, is still considered a large tube. This makes the impressive scale of the R|Z568M, featuring 50mm digits, even more striking. The manufacturing process of an R|Z568M tube is documented in this video.

The DGM01 is a modern Nixie tube produced by Sadudu and his company iNixie LAB in China, comparable in size to the Soviet IN-18. Like the R|Z568M by Dalibor Farný, the DGM01 is assembled by hand in small quantities. Each digit in the tube has a distinctive design, with the numbers one and five standing out in particular. Notably, the DGM01 features a right decimal point which is unusual for tubes of this size and was specifically incorporated for use in replicas of the Divergence Meter from the popular anime series Steins;Gate. Unlike the R|Z568M and tubes made by Millclock, which have a large metal bases, the DGM01 utilizes proper pin-to-glass seals, enhancing its authentic appearance. The glow discharge exhibits the characteristic blue tint seen in tubes containing mercury vapor, which is indicative of long-life Nixie tubes.

The ZIN-70 is a modern Nixie tube and, with its 70mm digits, ranks among the largest ever produced. Handmade in limited quantities by the Ukrainian company Millclock, it is available both as part of their Nixie clock range and as a standalone component. Its construction bears a strong resemblance to another contemporary Nixie tube: the R|Z568M, manufactured by Dalibor Farný and his company. A comparison image below shows the ZIN-70 on the left and the R|Z568M on the right.
