I'm a huge fan of the Gridfinity organization system, and I also have a butane blow torch that I use for burning and melting the strings off of my prints, and there wasn't a convenient holder already available for it and it's flared bottom, so I made this one using this as the base:

It takes up 2x2 gridfinity slots, and has magnet holes on the bottom for securing it to a base plate.

I printed it in Sunlu Orange PLA+ at a .2 mm layer height and 25% infill.
