I'm Jinseo. Today's makerspace is for free observation, so you don't necessarily have to make anything. If you want to test the bookstand, I can adjust the height for you, and it's also fine if you just want to look around. This is the first version I made at an angle that's comfortable for me, so I don't know yet if it suits other people. I'd love it if you could start by telling me what posture you usually read in. Rather than saying I'll fix it right away, I'm practicing thinking about it together. I hope we can continue talking about this item at our next meeting too.
