Try harder lol, I really don't know what else to say. Nothing is impossible; If you wanted to make quality keycaps on the same level as ETF you 100% can. Don't act like these makers are supernatural beings with skills us mere mortals could never possess, its plastic shaping guys cmon.
That being said, I am currently working on starting my own artisan keycaps - I'm sure most of you will boycott my keys because of how unfavorable my opinion is, but it will be on geekhack eventually. So there's that.
No one said anything is impossible, however the likelihood of any one becoming the next ETF or KF or whatevs, is slim. Mechanically caps might be easy to make, but I think you're gonna be in for a big wake-up call if you decide to become a creator your projects are low effort. Low effort will show over time in your caps, and you will not keep up. People that don't see anything but plastic and glitter won't make anything good, the same way that if a person sees a log and only sees firewood instead of a sculpture or table etc. That type of thinking is just edgey-keebro reductionist bs.
Keycap making (any art) if anything is an "experimentful" process which, as you can see by all the different colorways and sculpts, is a test of your creative abilities and inventiveness.
I wish you luck in your endeavor and look forward to seeing your sculpts, however if you think most people will remember you enough to boycott you after today, you're probably mistaken.
