Wrong Sized Holes

This is the top panel for a new creation I’m working on. I want to make a pixel ring surrounded by pushbuttons. So I added a pushbutton button ring element to my design program and then printed it out.

Of course, after a two and a half hour print I then discovered that all the button holes are too small. You can see in the picture some of my attempts to make the holes bigger, but PLA (which is what I printed it in) is horrible stuff to work with.

Moral of the story: If you’re printing things with holes to fit other things into, perform a tiny test print with just one hole to make sure the size is right before you go and print the whole thing.
