This is a soldering iron stand, that features minimal wasted material. It has a couple of accessory cutouts in the bottom for sponges, or extra tips. It is designed to print support-free. My iron is from harbor freight, and has a pretty common exterior size. The stand should accomodate most irons up to 25 mm outer diameter in the front, and 18 mm outer diameter in the rear. I printed this out of ABS, however as long as your iron's handle doesn't get too hot, you could likely print from PLA or PETG and be fine - obviously just use common sense and take precautions when dealing with fire risks.
