Oh, I see. I didn't know the window plastic itself is considered a second layer since non-doubleshot, stock keycap sets come with windowed keycaps such as Num/ScrollCaps Lock. (Ex: Leopold FC200R)
That depends, I'm not sure how OEM keycaps achieve the windows in the keycaps as they are usually just a small piece of clear plastic (I have an FC200R and looked it up, it's not molded into the keycap as there are tiny gaps between the clear and solid plastic, so it's not doubleshot), but as I mention in the video, the clear plastic on Cherry keycaps is definately a second layer and therefore doubleshot.
I posted this to reddit. If you want me to pull it down let me know. I don't bite.
I don't visit Reddit but I don't mind
Watched this yesterday, great video! I script wouldn't hurt, but who am I to complain.
I'll write one next time first, I promise!
