I made this test block to test the fit on some holes (my printer isn’t calibrated), when I noticed the problem. The cone on the side was a sanity check for this problem.
I tried googling but couldn’t come up with this same problem.
Edit: I did just figure out a way, I made them a union group, which applied the cuts immediately, and they stayed when exported. I’ve never had to do that before. Though admittedly that’s probably the right way, I normally use fusion360. Something is definitely weird though. It should just work without doing that. And in fact it did a few days ago on a different project file.
You probably clicked on the square, then when you went to export it automatically selects “export 1 piece.” Make sure to check export all. I have a grand total of 2 hours in tinkercad and that’s something I ran into. If that isn’t it, I got nothin.
Thanks! I did try this, and variations on this, by selecting all and clicking export all 6 items. No dice.

I always use union-groups when working with holes. Sometimes I even have to go through multiple nested union groups to get the desired result. But it always works when exporting, and you directly see the resulting shape in the editor (and the export).
