All you need is a ruler or calipers, a vector graphics program (Inkscape is free)
Step 1: Measure
Measure the dimensions of your products
Step 2: Download Inkscape
Open your vector graphics editor (Adobe Illustrator, CorelDRAW). You can download Inkscape for free, if you don't have one.
Determine the geometry for each panel, and begin by drawing an outline.
Step 3: Add Fingers
For .59mm plywood it is best to use fingers of .59mm. Make a .59mm square and position it in one corner
Step 4: Copy the Fingers Along the Whole Side
Step and repeat all fingers, spaced .59mm apart
Step 5: Merge the Fingers to the Panel
Weld all the pieces together in one piece, then offset the piece outward by 0.01mm to compensate for the KERF (the material that the laser would incinerate)
Step 6: Delete Old Object
After the offset, break the contour apart and delete the original shape.
Step 7: Repeat for Every Panel and Submit Design to CutYourWay.com
Repeat for every panel. Remember that where you have fingers on one panels, you should have holes on another panel (you can line up pieces to make sure they fit right)
After you are done with the design, submit your vector file to Outfab.com
Step 8: Sand the Parts
After you receive your parts sand them with fine grit sandpaper (150 grit works well)
Step 9: Put the Display Together
Now you are ready to put the display together with a mallet or a small hammer
Step 10: Optional Nails
If you like belt and suspenders, hammer in a few very small nails or use clear wood glue on the inside joints. Static friction is usually more than enough to keep everything together without nails and glue.
