I'm choosing to analyze my soldering iron which I inherited from our WFH-era while I was working at a small tech company.
The iron itself is dark blue and yellow and doesn't make any obvious attempt at gendering. Actually, something about the choice in shapes and colors makes it kind of look like a kids toy. Both the base and iron stand are labeled HAKKO. The base has a big black toggle switch for power. It also has two buttons labeled "UP" and "ENTER". These are for changing the temperature of the iron but I've never needed to change that so I don't know how those buttons work. Intuitively I would think a "DOWN" button might be necessary as well. The model number is also labeled and there is a logo stating the solder station is "ESD safe" meaning it is safe from electrostatic discharge which could break electronics. The base has also been customized with a tin of chip quik stuck to the top of it.
I would consider this a STEM object soldering is when a melted metal is used to join to other metal objects. This process is used largely in the building of circuits/circuit boards. So that falls under the technology and engineering categories of STEM.
I guess my soldering station might feel a little bit more accessible to me if I took two seconds to look up its manual. But in all seriousness, when I think about when I first started learning to solder I was really shaky and scared that I would break the circuits I was working on. Basically I was always scared of breaking things when I first started working as an engineer and that really held me back from learning and doing my work. I think STEM fields in general would feel more accessible if we were taught that it is okay to make mistakes, break things, and even fail.
