Write a Python program that allows a 3D printing workshop to calculate the total cost of printing a custom model.

The program should:

• allow the user to enter the total volume of the 3D model in cubic centimetres ($c{m}^3$) (no validation is required)
• allow the user to enter the number of support rafts requested (no validation is required)
• calculate the total printing cost by:
  • charging £0.45 for every cubic centimetre ($c{m}^3$) of volume
  • charging a further £1.80 for every support raft requested
• output the final calculated printing cost with an appropriate message.

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