I printed the box with a 0.8 layer 0.3 nozzle (0.4 nozzle will take an unforgivably long time to print). "cover" and "lock" to print nozzle of 0.4. "lock" to print the 4 walls without a roof\floor-filling 0 for a color result with a layer height of 0.2, you need to change the color on the 23-24 layer
