Write a program (using pseudocode or a programming language of your choice) that allows a 3D printing laboratory to calculate the total print job cost for a customer.

The program should:

• Allow the user to input the expected print duration in hours (no validation is required).
• Allow the user to input the weight of the plastic filament requested in grams (no validation is required).
• Calculate the total print job cost by:
  • Charging £4.50 per hour of printing time.
  • Charging £0.12 per gram of plastic filament.
  • Adding a flat-rate setup and machine-preparation fee of £8.50.
• Output the final total cost with an appropriate user-friendly message.

You should use meaningful variable names, correct syntax, and appropriate indentation in your answer.
