Freecad doesn't show me that from the step file input either. > At the risk of ruining the job, you can tweak prints with a soldering > iron and a retired tip. In this case, I think I'd druther center it up in a 4 jaw, and bore it with a very sharp tool, say about half a thou per pass, or less, I can go .0002" at a time in diameter with my hand dials on the Sheldon. .0001" in radii. Be a good excuse to find out how out of tram this Ender-3 is that is being corrected by the bed levelers, but that won't fix the axis lean. And the Sheldon's spinning will easily detect that. I may yet drill access holes in the left post for the X bar leveling screw's access, as it not exactly plumb visibly. Said another way, if it was setting on a dead level surface, a good Starret level, on the X travel bar, will show a bubble left of center by quite a bit. But there is no access to those two screws once the extruder carriage is mounted onto the post, so if its factory miss-adjusted OOTB, you've no way to fix that without drilling holes in the left post center web for allen wrench access. Or take it back apart, make the adjustment, and put it back together to check it. Needs to be done in any event if making rotating parts. And these are.
