and that worked surprisingly well. I drilled out all the holes and even cut away the rectangle for the RP2040-Zero board.
The toner transfer for the F.Silkscreen was not so successful even after a couple of attempts. I think it's because I sanded the fiberglass. I just retraced the parts that didn't transfer with black marker.
I soldered the components to the board, and it all looks great, until you realize I soldered the RP2040 board inside-out... I need to fix that tomorrow.
