Learn how to make this modern, artistic, yet simple lantern from recyclables. The design can be resized to fit different materials and accommodate different light fixtures and looks wonderful in multiples as indoor/outdoor lanterns for special events such as weddings.
List of Materials
1. 2 Sheets of 12 x 18" 1mm Cardstock (approx. 300 mm x 450 mm)
2. About 200 Recycled plastic spoons
List of Tools
3. Hot Glue Gun + Glue Sticks
5. Exacto Knife
6. Gold Spray Paint
7. Laser Cutter (if you have access to a local makerspace!)
Step 1: Download the Template for Spiral Core
Download the provided template for a spiral sphere. The vector drawing file is named "spiral.ai" and can be opened using Adobe Illustrator or Inkscape (which is a free vector drawing program). It is laid out for a 12 x 20" document because that's the cutting bed size of the laser cutter at my local makerspace.
You will need two cut sheets, or a total of 10 pieces (5 from each cut sheet).
I roughly modeled the slices in Google Sketchup using the "Unfold" plugin and then experimented with different curvatures and widths until I got a nice shape with 10 pieces.
Step 2: Cut the Spiral Core Pieces
Once you have downloaded the template for the spiral core, you can do one of two things. You can print out the files in PDF and use scissors to cut or an Exacto knife to carve out the outlines. Alternatively, if you have access to a makerspace, you can use a laser cutter to do the work for you. A plotter cutter will also work fine.
Step 3: Learn to Assemble the Spiral Core
The first step is to interlock the 10 spiral pieces as seen in (A).
Next, flip the entire thing over while holding the interlocked center.
Now, starting from a piece of your choice, interlock the top as shown in (B).
The top of the interlocking dome should look like (C).
Finally, the assembled spiral core as seen in (D) and (E).
Once you have mastered this step (it might take several tries) you can disassemble the pieces. We'll be reassembling them again later following the same steps after gluing on the spoon tips.
