My plan is to 3d print a giant scaled up version of the bones of a hand, complete with ligaments, tendons, and magnetic attachments.
Now, when I go to 3d print it, I'm hopefully going to print several bones at the same time, and when the printer gets to a certain height where I can access the holes to put magnets in, it will pause and wait for me to put in the magnets. Because of that, ideally all of the holes are at the exact same height (from the build tray, so the same z height in blender I guess), so I only have to pause once. Is there a way I can select all of the "holes" from several of the bones and snap them all to some imaginary z plane? This would rotate each bone in a different way so that the "holes" all ended up at the same plane. Does that make sense?
