I’m fairly similar to this myself. I don’t really care too much about my gender identity; it feels like if I woke up tomorrow in a female-presenting body, I’d be totally fine with being a woman. At the same time, I don’t mind being a man, and don’t have any strong desire to change anything.
At the end of the day, I don’t strongly identify with being either male or female, so I’ve just called myself gender apathetic. I stick with he/him pronouns because it’s easiest, but I’d be fine with any other pronouns as well. I’m me, and that’s the most important thing.
Any chance you’d be willing to share the STL? I have a 16 inch portable monitor as well and I kinda want to try this when my new printer arrives.
