I often print holes into my 3D things in order to either attach them to something, to each other, or attaching things to them.
So, I purchased a kit of metric "screws" / nuts and bolts:

They work great, but sometimes I don't want to use a nut with the bolt. So, I've sometimes just printed a whole *slightly* smaller than the screw and tried to use the screw to self-tap into the plastic. Sometimes heating the bolt with a torch and screwing it into the plastic would also help "tap" the hole.
Well, I stumbled on these little gems and they arrived today. I tested them and they work GREAT

I'm LOVING these things! Sure, the hold isn't going to be as strong as having a nut/washer on the other side, (or even cooler, an embedded washer), but this is a quick and easy way to get a "good enough" hold for most of the projects I'm working on!
