Fairly newish, however learning very quickly.
We just upgraded to a Prusa Mini and one of the first things I wanted to print was a case for my boy's Switch game cards. I finally found the perfect one, put it into PrusaSlicer, and got ready to print only to realize I had absolutely no idea if the size this thing was printing was accurate. Well, I knew it wasn’t accurate because the box was taking up the entire bed. I came across a few other things I wanted to print to enhance other outside objects but quickly hit the same wall.
What in the world can I do to solve this?! I tried to measure the opening for the game card but I still don’t think it was measuring correctly.
