That's so weird I was just wondering about trying just that. Will let you know if it works!
Even when I rotated the copper pad on the right side 180 deg. it didn't work... The right side of the blocker/copper has to be touching the board... weird!
It's a go! Have and a excellent day and thank you for making these files!
Can I get a more n00b-friendly explanation for how this works?
I'd like to import a custom shape (like a logo) that blocks out the soldermask.
