But a .5mm shrink of the bore was almost too much, 0.25mm would have been just right I think, as I had to dull the edge of the hub that plugged into it, and drive it together with a rubber hammer. And barring a massive filament failure loosening it, its there forever. The shaft hole is pretty sloppy, so I'll not finish this one with grub screws. But now I know I can do it.
