[Python] vPython 3D Printing?

I have my school final year work that shows that you can use Python for 3D printing and I'm using vPython and I created some basic model of snowflake out of some boxes and rotating them but now I'm concerned of converting it into like STL file for 3D printing. I tried everything but unfortunately still without outcome.

I've tried different variations of libraries that can export it into stl but still nothing works. ChatGPT gives me some answers but nothing works and even more errors comes out.

I know that the snowflake isn't perfect but I just made some basic object to try to export it into 3D printable object how it would look and then I would work on some harder and cooler objects.

from vpython import *
from time import *
import math
import numpy as np
from stl import mesh




#Snowflake - sf
stripLenght=5
stripWidth=0.2
stripDepth=0.2


#box_obj.rotate(angle=radians(45), axis=vector(0, 1, 0), origin=vector(0, 0, 0))




sf_strip_horiz=box(color=color.cyan,size=vector(stripLenght,stripWidth,stripDepth))

sf_strip_vertical=box(color=color.cyan,size=vector(stripWidth,stripLenght,stripDepth))

sf_strip_rotate1=box(color=color.cyan,size=vector(stripWidth,stripLenght,stripDepth))
sf_strip_rotate1.rotate(angle=radians(45), axis=vector(0,0,1),origin=vector(0,0,0))

sf_strip_rotate2=box(color=color.cyan,size=vector(stripWidth,stripLenght,stripDepth))
sf_strip_rotate2.rotate(angle=radians(-45), axis=vector(0,0,1),origin=vector(0,0,0))
