Overview: This post goes common methods of connecting parts together. You will learn how to make good joints / connections to fit your needs. This is useful for parts that move or are too large to print.

Please note: Connections after printing seem to be to hard, over time they will weaken. So it's probably better to have a hard to connect object at first. 

Snap

These are the most common and work very well even after time. They allow movement. 

Noticed that it both of these you can modify the part to make it easier. Both use slits that allow more flexibility. 

Ball

This is the typical arm joint you will see in an arm. It allows your object to rotate in all directions. 

Chain

This is something unique to 3D printing as you can print a chain without any breaks. It's a beautiful feature of 3D printing. 3D Printed Clothes are using this method. 

Mid-Print

Of all the connections this is probably my favorite because the final resul makes us awe and wonder. We have all arent the boat in the bottle and wonder how it got in there. With 3D printing you can do this, as well as even more. While something is printing, you can add other objects to it. A really simple example is this cube that you put a coin in while printing. 

Overall there are many variations.
