Large Calibration Square

thingiverse

As if another calibration print is needed... A large square used for calibrating the axes on your 3D printer. Only uses 1000 mm^2 of filament. SketchUp file is included. Instructions 1) Print out this thing. I used 2 perimeters and 30% infill. 2) Measure your thing with calipers. It should be 105 mm square on the outside and 95mm square on the inside. It should be 5 mm tall. 3) Modify your step value with the equation: (old steps per mm * defined object length) / measured object length = new step value
