Why I love 3D printers

I draw it and then I can hold it.
It builds up in tiny layers, over and over.
If it does not fit, I change it and print it again.

You can love 3D printers in Caldwell.

What it really is

A 3D printer builds an object one thin layer at a time.

Three things to try today

Draw a part you wish existed.
Measure something it has to fit.
Write down the measurement to the millimeter.

For the grown-up reading this

A child in Caldwell, ID who loves 3D printers is not unusual. A child in Caldwell, ID who is told that loving 3D printers is unusual — that is the problem. Caldwell has a population of about 48,957.

Tolerance is the lesson. A part that is a millimeter off does not fit, and that is the point.
