Ball Lift 4 (Screw)

Typical archimedes screw vertically, lifting marbles

this was just me practiacing with physics and this time practice for using arrays and curves

the screw was made by making a curve in the shape of the screw thread, flattening a cube and creating an array, to follow the curve using modifiers, the cube has one side lifted to give it the inwards bank to help keep the balls in
