...After spending a few hours designing and getting the cup size and handle shape how I wanted it, I processed the model into the .stl format and sent it to print. A few hours later and it was complete! ...
...To give an idea of the cost this was 95cm3 of PLA plastic which works out at 10p per cm3 so the cup was £9.50...
A couple of 'a few hours' sounds like a very long time, and £9.50 for cup?? would it not be a lot quicker and less expensive to pop to the shop and buy one off the shelf??
