I have a Nixie tube clock, unfortunately the tubes sometimes fail and though the board has sockets for the IN-14 legs, the legs are quite often slightly bent or just angled incorrectly making it hard to insert the tube.
I made a variety of acrylic (3mm translucent pale blue) guides. I went from 0.5/0.6/0.7/0.8/0.9/1.0/1.1/1.2/1.5/2.0 mm so I could easily insert in the 2.0mm guide and gradually ensure the legs were straighter with decreasing hole size.
Yes, I’m aware it’s solder in place. OP said that he was inserting the IN-14 into sockets. As he said, these are not to replace the original spacers (which my case of IN-14s had), but to straighten the legs for insertion with decreasing hole size.
I will add, that if you need to insert the IN-14s for soldering, there is a really easy method. It’s to start at one of the leads and start trimming each one in succession as you work your way around them. You’ll end up with a vertical spiral of leads so you can insert the longest one first, followed by the next one, etc. Super quick and easy.
Sorry for the delay. I use the Manufacture Workspace in Fusion 360 to create the toolpaths I want. Then, I output them via the Glowforge Colorific post processor. It turns the toolpaths into an SVG that the Glowforge UI can read. Search for Colorific in this forum for more info about the post processor
