IN-12 Nixie Socket
thingiverse
This is a model of the socket for IN-12, IN-15 nixie and IV-22 VFD tubes, carefully crafted in OpenSCAD from detailed datasheet information and precise measurements taken from an original bakelite socket. I deliberately omitted pins 13 & 14 because I don't have any tubes that utilize them. There are several other high-quality IN-12 socket designs available on Thingiverse, but I designed this one specifically to provide the OpenSCAD source code for further modification or customization - I have no intention of using it as is. The default diameter of the pin holes is exactly the diameter of the IN-12 pins, so you'll need to measure the diameter of your contacts and adjust the pin hole size in the customizer to create a working socket. Data and photos of an original socket can be found at http://www.tube-tester.com/sites/nixie/data/soc/SK-136-12pin-chassis-russ/SK-136-12pin-chassis-russ.htm
