This is a set of feet for the Wanhao Duplicator i3 Plus printer. These should be printed in TPU to provide stiffness plus vibration absorbing and also to stop any movement or creep during printing. You require x8 in total to provide the required stability.
They are a simple adaptation of the model from imgineering4 found here
Due to the varying thicknesses on the frame you will require
x4 of i3Plus_foot_v1 (for the front and rear of the main control unit)
x2 of i3Plus_foot_v2 (for the front of the gantries)
x2 of i3Plus_foot_v3 (for the side of the gantries)
