I added provision for a 2.5mm or 3mm grub (set) screw less than 4mm long each to lock the brush in place. It might be an inconvenience to pull the brush out quickly to clean it, but better than losing it to the vac. You could try to snug up the grub screw to apply a little friction and still be able to pull it out without backing off the screws. I also made the hole insert for the brush closer to a standard 1/8" shaft, typical for a Dremel tool.
