Nice nixie clock, laser cut acrylic and stainless steel allen bolts. Originally I wanted to design the PCBs for this myself but I realised that there were plenty of kits already out there doing exactly what I wanted. I still use this clock every day - it makes me cheerful for some reason. The kit I ended up using was from Tube Hobby and the files for the laser cut sections are available here. Be aware, however, that there are two grooves to cut in one of the centre sections - I used a milling machine, you could probably get away with a Dremel.
