Very quick and easy print for a very silly idea.
Technically requires multiple materials, but can easily be printed using a single-material printer by slicing both models individually at the same position, then swapping the material after printing the pink/magenta. With an 8mm nozzle at 20mm/s I was able to print the whole thing at 10cm x 10cm in under an hour.
The author marked this model as their own original creation.
