Hole cleaner

Quick solution to a simple problem of accuracy (or CAD mistake in my case) for a printed holeSo after printing, if the small bearing woult not enter the hole… and for some diameter, there is no simple tool, a drilling bit is not efficient.That pieces are made for a 8 mm and 6.35 hex fixation, use a folded piece of sand paper and 20 seconds after you can use the hole as planned.On the pictures, the 14 mm hole was 0.1 mm to strech and there was a seam of 0.1 mm.
