This instuctable will detail how to make one of the stones from The Fifth Element. For each stone you will need: around 6 inches of wire, two springs, one AAA battery, a maker-bot, and an LED the color of the element you are creating.
Step 1: Body
First, draw an equilateral triangle with each side 40mm long. Next, boss extrude the triangle to 100mm. Now extrude cut a smaller equilateral triangle (sides 29.6mm) 25mm into the top of the triangular prism. close the cavity with an identical triangle placed over the top of the hole 3mm thick. Your stone should now look like this in cross-section veiw:
Now, draw a circle with diameter 15.5mm centered on the other end of the triangular prism and extrude cut it to a depth of 72mm. Centered at the bottom of this new hole, draw another circle 5mm in diameter and extrude cut it Up To Next. your stone should now look like this when in cross-section view:
Now, draw the sketch in the picture and extrude it to a depth of mm. (note, make sure to make the sketch on the same end of the triangular prism as the previous step) next, make a hole at the bottom of each sunken tab created by the previously created feature. the hole size is M2X.40, to a depth of 10mm. the finished cut should look like the second image. last, create a plane exactly halfway into the triangular prism from the side. draw a half-circle with a radius of 6, centered at the top of the prism (the smooth end)on this new plane. last draw a circle on the top of the rectangular prism with its center on one end of the arch previously created and a diameter of 4mm, and swept boss the two sketches. The result should be a small hook ring as shown in picture 3. You are now done with the base that you use for all of the stones.
