Had to print the main gears at 105% x and y. The main jaw needed a bunch of sanding to fit. I think the clearances are for a better setup than mine. It's still sticky at certain points.
That said, I love the concept and it's functional. The threaded rods are a bit fragile when printed vertically. They can break at the base easily. I printed the main jaw 3 times because I'm clumsy.
