Extrusion multiplier calibration cube
thingiverse
This is a precision-crafted 20mm x 20mm x 20mm cube with an open top and precisely engineered 0.8mm walls. I rely on it to fine-tune the extrusion multiplier for my slicer when working with fresh spools. To begin, set the multiplier at its standard value of 1. Next, switch the extrusion width to manual mode and enter a setting of 0.4 (perfectly suited for 0.4mm nozzles) before initiating a print of the cube. Upon completion, take precise measurements of the walls and calculate an average from all four sides. Then divide 0.8 by this calculated value to obtain your exact extrusion multiplier.
