September 23rd

Vic took the van and headed for the hills to (hopefully) get a few nights of proper sleep without being woken up a couple of times a night by Tilly.

The rest of us went to the airport - too late to fly Young Eagles, but early enough to get lunch and see the Airventure / kids' scholarship presentations.

We spent a fair amount of the reset of the day watching the 3D printer.

I did have an interesting interaction with ChatGPT, as I'm too lazy to do the maths.

what percentage would I need to increase the size of a 1/3 cup measuring cup to get to 5oz in a 3D print?

To determine what percentage you would need to increase the size of a 1/3 cup measuring cup to achieve a volume of 5 ounces in a 3D print, you can use the following formula:
Percentage Increase = ((Desired Volume - Original Volume) / Original Volume) * 100

So, you would need to increase the size of the 1/3 cup measuring cup by approximately 87.5% in a 3D print to achieve a volume of 5 ounces.

remember volume increases much faster than area

You're absolutely correct; when scaling three-dimensional objects, volume increases much faster than area. To achieve a specific volume increase, you would need to consider the cube root of the scaling factor.
In your case, you want to increase the volume from 1/3 cup to 5 ounces. As mentioned earlier, 1/3 cup is approximately 2.67 ounces. So, you want to scale it to 5 ounces.
Let's calculate the scaling factor:
Scaling Factor = (Desired Volume / Original Volume)^(1/3)

So, you would need to increase the size of the 1/3 cup measuring cup by approximately 21.7% in a 3D print to achieve a volume of 5 ounces, taking into account the fact that volume increases more rapidly than linear dimensions.

I'm not worried about the Terminator just yet.
