The Thing he uses for the lures could just as good work for a slingshot, you shot insert a wire on both sides and let it rotate slowly, it becomes completely even as Epoxy "self-balance" itself thanks to surface tension
Of course you would need high viscosity epoxy
And yes 25 pairs for 6€ isn't cheap but nether is it expensive, its an okay price
I do not have a servo, and do not know where to get one. I have a drill though, but I can't have it rotating for hours because then it would break.
