Design for a nixie clock with miniature nixie tubes IN-2

Hello everyone, I'm planning to build a similar nixie clock like here: But with different nixie tubes, the miniature nixie tubes called IN-2. They are round in shape and just about 15mm in diameter. I think I can find its schematic and PCB files but as always a good design for the casing is a challenge. I would appreciate if you can share guys your ideas for the casing for such a nixie clock. Cheers!

Use one of the published digital clock circuits that puts out a BCD (binary Coded DEcimal) format, and then drive the nixies with binary to one-of-ten driver ICs or binary to decimal decoders. No need to design the whole clock circuit.
