Roll adapter for old cameras

Hello, would it be possible to print this small part 4 times? 

It is to be used as an adapter for current camera film roll (format 120) to a former size that doesn't exist anymore (format 116). In other words: enlarge the current small roll, by applying an adaptor to each side of the roll, to make it bigger so it fits into the camera! See picture with current roll on the left and former roll on the right.

The part does not need to be particularly strong; but could it be possible to reinforce the pimple?

Thanks! :-)
