Just in time for Halloween, this is a redo of my large articulated, snap-together, 3d printed spider. It is half a meter (about 20 inches) across when built. This is version 2.0, I made the original one about a year ago. That one was good but I have made a whole host of revisions making this one much better.
This is a pretty big print project because of the size and number of parts required. So give yourself plenty of print time and keep your printed parts organized. The body is made up of a top and bottom section. The bottom (lower) section has two print-in-place snap lock hinges to hold it together with the top section. And, the leg assemblies are all held in place when the two body sections are snapped together.
Conventionally the spider has 8 legs (four on each side) and the front and back legs are longer than the two middle ones. But you can actually build it however you want.
All the leg joints are articulated and have a click mechanism so you can animate the spider however you want.
