If you're an amateur TIG welder like me, you contaminate your tungsten electrode regularly. Dipped your tungsten in the puddle? Pull it out of the torch and drop it in an empty hole in this caddy (take care to put it in “cold” end first) and grab a freshly sharpened one to replace it.

This is a simple print that will hold up to 12 tungsten electrodes up to 1/8" in diameter. The bottom of the holder has 2 holes to glue in optional 1/4" diameter x 3/4" long neodymium magnets to hold it in place firmly on a steel table or other steel surface. I recommend printing this out of something with a moderate to high temperature resistance, but any plastic is likely to start showing some wear and tear after a significant amount of use.
