I lost the folding wire safety stand that came on my hot glue gun some time ago. Modeled this so I could stand it up again without printing an entire docking station-kind-of thing. Uploading in case anyone else needs it some day. I don't know if it would fit any/every glue gun. But mine is a fairly standard size. The prongs that go in the gun have a 2mm diameter. 

I printed mine in PETG. I wouldn't recommend printing this in PLA, since it needs to bear weight and flex a little to do its job. I'm also not sure PLA could withstand being so close to a heat source. ABS would likely work but I haven't tested that.
