Using a GT2 pulley (7 replies)

Hi all,
This may sound like a stupid question but, would it be possible to use a GT2 pulley as a (mini) hobbed bolt ?

the interior is 7.2mm and combined with a 608 berring to conpress the filament onto the pully.. could that make a good grip for ABS / PLA ?

Just thinking out loud here :-)

Thanks,
