Chains

The very first thing I printed on my Replicator 2 was one of the default models included on the SD card, a chain.

Chains are a pretty cool example of what you can easily create using a 3D printer. Trying to machine something like that would be a much more difficult task, and certainly couldn’t be done in 12 minutes.

Inspired, I made a couple of my own chains in Tinkercad.

As cool as this is, there are readily available parametric chain generators written in OpenSCAD that are much more practical and powerful, so I lost interest pretty quickly.

But there is more than one type of chain, and they don’t always have to be connected during the print. Thus began my ongoing interest in snap-together 3D-printed parts.

I started with a fairly simple two-part chain built in OpenSCAD:

From there it quickly led to what I just created!
