Seems Harbor freight may have changed their chisels a bit. They don't fit too well. I printed it with the Gridfinity bits below the plate since I don't have that system so the bottom of mine is flat but still has full contour for the chisels.
No problem. Just pointing it out so you can note it in the details of your model so people don't start complaining. I appreciate the effort. It's close enough to keep mine where they belong.
