Actually I just remembered I actually have an example of a "standard" ER32 nut that would work with a solid collet. I don't know it's origin (it came with a used machine we bought) and I don't actually have any solid collets to test it with. But the lip on the inside of the nut that a normal collet snaps into only goes 180° around the inside of the nut. When the nut is unscrewed you can tip the collet to one side and remove it from the nut even with a tool inserted in it. When tightened the tapers hold the collet centered and when removing them, the 180° of the lip that is there, still engages collet to pull it out of the spindle taper same as a normal nut.
