Simple knock down stool made from plywood (flat pack)

I was given a few 90 x 180 cm (3 x 6') sheets of slightly used plywood which I am in the process of repurposing.
Since I have use for a couple of extra stools occasionally, I recently drew this slotted (flat pack) stool in Sketchup.
I designed it so that two complete 48 cm tall stools will fit onto a 90 x 180 cm (3 x 6') piece of 12 mm (7/16") plywood.
It could easily be cut with a laser, or a CNC router (I cut it manually with a jig saw and a circular saw).
(Click on the [i] at the top left of photos to see an enlarged version.)

Materials used
- 90 x 180 x 1.2 cm piece of plywood (slightly larger than 3 x 6' and 7/16" thick)

Tools used
- Handheld circular saw
- Handheld jig saw
- Power drill (and 8 mm bit)
- Small orbital sander

1. March 22, 2012 - as per request, I have added a PDF file of the cutout plans. Red outlines indicate the 3 parts that are necessary if you want to print and make templates. Note: slots are sized for 1.2 cm thick plywood (overall design is 180 x 90 cm).
2. For those of you who have a CNC router, I have uploaded slightly modified version of this stool to Ponoko.com.
   You can cut it yourself, or have Ponoko do the production for you.

Step 1: Plywood stool plan layout

I designed this stool so that two could be made from one piece of 90 x 180 x 1.2 cm plywood (they will fit onto a 4x8' with room to spare).
I have attached an EPS outline file to the first step, and it could be converted for use with a laser or CNC plotter.
*Note that the slots are made for 1.2 cm (7/16") plywood.

for those of us that do not have a program to easily access an EPS file ... could you please post it in a different format to make printing out a template possible

thank you in advance

I have uploaded a printable PDF version of the cutout plans (above step 1). As in the attached sample image below, the design is flipped around, so if you can tile print it on a normal printer, and you want to make templates, just print out the area with the three parts in red.
*Note that the slots are for 1.2 cm plywood.

Below is a page on the Adobe site with information on printing tiled PDF files.

Thats really cool! I love the simple slotting design. Pity I don't have a circular saw :( I'll just jigsaw my way to a crooked chair then ._.

Oh, I wouldn't use a router for a clean top. Part of the joy is seeing how the flat pieces fit together like a puzzle! But what did you do to secure the top to the legs? People will automatically grab the top to move the stool, and it shouldn't come off. Did you glue it?

I've attached a closeup of the seat showing a hole and leg tab.
The legs have a slight angle, so the tabs are wedged into the holes in the seat.
If this was cut by laser or CNC router, the fit should be tight enough that the top piece is secure.

It's great you're sharing these plans. You could probably sell them to a company like Ikea.

Thanks - I'm currently looking at a few different options, something along those lines.

This is awesome. I've needed one of these in my kitchen!

Thanks! Here's a rendering of what the stool might look laser cut, or painted with bright primary colours.
