Of course, you’ll need 4 springs. Here are a few considerations when choosing upgraded 3D printer bedsprings: RigidityThe replacement springs are more rigid than the stock springs, increasing consistency between prints and reducing vibration. LengthThe replacement springs are the same length as the original springs, meaning you shouldn’t need to adjust your Z-axis end-stop like you would with longer springs. ShapeThe replacement springs feature a flat top and bottom (vs. The stock springs’ rounded top and bottom), resulting in less spring movement or shifting during and between prints.
