Give me a Python code that will work as a random number generator to print a multiple of 3 from 3 to 3000.
The `random` module will enable you to generate a random number to your specifications. Here is how it's used:

# import the random module
import random

# get a random multiple of 3
multiple = random.randrange(3, 3000, 3)

# print the multiple
print(multiple)

This uses `import` to load the `random` module, then using the `.randrange()` function to retrieve a random multiple of 3 from 3 to 3000. The `.randrange()` sets the start value as 3, the stop value as 3000, and the step as 3. The value it generates defines the variable `multiple` which is then printed with `print()`.
