A2L Mounting Holes

Anyone happen to remove the bottom cover from their A2L and have the exact dimensions of the internal sections of the mounting holes? I looked at Bottom Cover Replacement Guide for the A2L | Bambu Lab Wiki, but there’s little information; I’m looking for the internal details of these holes:

I guess a high quality STEP (or STL if STEP is unavailable) file of this would be even better.

Thanks.
