Cartesian coordinates/XYZ axis

Educational visual representation of 3 dimensional space. Made it for my child to aid in understanding basic 3d printing concepts. Only one small support needed. Can be printed with multiple colors for better aesthetic, or airbrushed as I plan on doing. Printed on one plate in four separate pieces and glued together. With a .4mm nozzle printing PETG it took 1h51m and approximately 67.8g of filament at 10% infill. The cube is 62.5x62.5x62.5mm, the axis are 100mm long with 10x10mm sides plus 1mm of lettering on the face.
