This is a 3d Printed tungsten grinder that has 4 fixed positions for the various tungsten sizes.
Per Jag (the designer):
This is an attachment for a dremel or similar tool that makes it easy to grind tungsten electrodes for TIG welding.
It has holes for 1/16", 3/32" and 1/8" electrodes at 4 different angles.
I'm using it now on my dremel using the "TEMO 10p solid 1.5" 40mm Diamond Coated Cutoff wheel disc 1/8 shk for dremel" I found on Amazon per one of the users' who tried this thing out. It does a nice job at grinding the tip down and the fixed positions ensure your tungsten never jumps off the grinder! WIth the 6 discs it gives you, you can have a separate wheel for almost all the material/rod you'll be working with. Pretty snazzy!

I'll be playing around with the results from a clockwise vs. counter-clockwise twist to see if my random question about the hemispheres of the earth playing a part in the arc control but I could never test that theory without a tungsten grinder, and with this I didn't spend $300-800 on one
