I designed "Woodpunk" in Adobe Illustrator. The patterns as attached are meant primarily for cutting by hand. If you want to use them on a CNC machine or laser cutter, they will definitely need to be modified!
When designing the lamp, I took measurements from an existing lamp I use at my workbench
. I noticed that all of the "arms" are made of equal-length sections, connected by triangular "joints." This made the design relatively easy - just two parallelograms with a "shoulder" at the base, an "elbow" in between, and a "wrist" where the arm connects to the reflector. Indeed, you will notice that is exactly how I labeled the parts.
In addition, there's the base and various spacers.
Everything is designed to be cut out of either 1/4" or 1/2" plywood. Since there are many identical parts, you can stack the 1/4" wood and cut it in pairs. Not only is this faster, it also ensures that the joints are precisely aligned (this is important for the arms and joints especially).
The patterns are intended to be printed out on 11x17" paper - if you don't have this capability at home, any business supply store or print shop will be able to print the patterns for you. I printed mine at work.
Also note that you may need to modify the design of the reflector section to suit the lightbulb socket you've got - the diameter may need to be increased or decreased, for example.
Included below are the preliminary patterns - I plan to clean them up soon, to make the whole thing easier to build!
A HUGE thanks to instructables user KChappers, who cleaned up, organized and converted my designs into .dwg .dxf and .cdr for me!
