You got to love 3D printing: The turnaround time from an idea to its execution is extremely short. Yesterday in the evening I had the idea for a spider ring (don’t ask – that’s the kind of ideas you get when you have small kids). Scavenged Thingiverse for a spider model, and found this very nice Creative Commons model.
Created a ring in Blender, added a stud to the spider, to make it easy to glue it to the ring, and printed the whole thing (actually, in two steps, first the spider, then the ring). The whole process took about half an hour. Nice.
You can find and download the final model here.
