How to Make (Almost) Anything

Project 2: Sitting Place Made of Cardboard

Background: I was excited to learn to laser cut. It seemed like a feasible first step towards making things in this class. I wanted to make a chair and think about how to make furniture that could be packed into my backpack and taken home easily. This allowed me a way to explore different types of joints. Eventually, I'd like to be able to design more ergonomic based furniture.

Lots of people have created incredible cardboard furniture. I wanted to make something that gave me a chance to experiment with the tools, while also being relatively simple in design. In total, this sitting place had two pieces to design that interlocked to make a place to sit.

Software used: I started with Inkscape and eventually moved to Adobe Illustrator -- where I knew my way around a bit more. Thankfully, there were only two pieces to design - otherwise I would have needed a more complex software. Adobe is okay at keeping measurements in tact - but if you need to change something, it isn't the swiftest software for making several repeated patterns.

Project 02a
Early sketches to show the size of the various pieces.
The measurements that made a difference were: the size of the laser cutting
machine (24 x 36") and the height or the thickness of the cardboard (0.18").
I found I could make the cuts fit at 0.186" to perfectly fit the other piece of cardboard.
Project 02b
The goal was to make a slightly undulating form that would create a natural nest for people to sit in.
Project 02c
This is the illustrator image. All the line weights were set to be hairline weight so
the laser cutter would cut (vector) the lines. Hairline weight in Illustrator is 0.001.
Project 01c
From the Illustrator file, I moved to the computer in the lab to use CorelDraw.
I made sure the hairline cut told the laser cutter to cut.
To prepare for the laser cutter, I had to cut cardboard pieces down to size so that they
were slightly larger than the pieces I wanted to make (10 x 30 x 0.18"). CorelDraw had a tendency to decrease the size of my image.
Be sure to check the scale that it the laser cutting is cutting at.
I also found the laser cutter would sometimes have send multiples of the same job to the queue. There seemed to be
no simple way to tell what job number CorelDraw had sent to the laser printer - so the best bet
for me was to clear all the jobs before sending a new print job.
Project 02e
This is the final version. I tested a few of the joints as I cut the boards by
originally making one of each side. The two sides fit together perfectly with
a width of 0.186". I found at this point that
while I could sit in it - it was not super comfortable. I packed the pieces
into my backpack and headed home to try it with a cushion.
Project 02f
When I returned home, I added a cushion and a model to show how it would be used.
I sat in it for a few minutes to test it out; with the added cushion, it was a perfect fit.
