Interlocking plywood chair

A plywood chair design that is assembled entirely without any fasteners, glue, or such.

The idea behind this project was to design a wooden chair that would be assembled without any screws, nails, glue or such. It was designed in AutoCAD and cut from 3/4" plywood using a CNC router. It's assembled by sliding the pieces together in an interlocking fashion, which makes for a sturdy build that's quite comfortable to sit on. The plan was initially for the backrest to be taller, but after seeing the full-size cutouts I decided to shorten it by two crossbars.

Enjoy this project?

I don't recall the model, but it was a ShopBot and the sheet in the picture is approx. 24" x 48".

STL?  :grin:  Seriously, though; this is a very attractive, sturdy looking design, which looks strong enough to be stretched sufficiently to be a three-seater bench.  (...with a bit of bracing.)

Thanks; it'd be cool to see a build or remix of it. I'll need to search some old storage media when I get a chance but I should be able to upload the drawing.
