[Mar 15] Joints Again

From last class' design, I noticed that the side could move towards the inside of the box. I can solve that by doing the same design on the other side. I went to the class an hour early so I can use the caliper in the lab. This is what it looks like:

My decision matrix for this design is:

Performance: ++

Manufacture: +

Aesthetic: ++

I ran my design by Oscar and cut it. Here is how it turned out:

The third piece could not go in because the edges wouldn't fit, although the size of the hole and the split were perfect. It was pretty durable in one direction, but if I exert enough force, it could be bent towards the inside because there is no third side in a different direction. I thought that it was reasonably prettier than last designs, so the actual decision matrix is:

Performance: -

Manufacturing: ++

Aesthetic: ++

Then I asked Oscar for help and we started from taping previous models together. We realized that three adjoined sides have to overlap each other in order to match up all the holes and splits. We also found out that the six sides are identical. I can construct the box by having two three-adjoined-sides together. Oscar recommended me to start from 1-inch sides. Therefore I drew another design as following:

The purple lines and black lines were for measuring purposes and were gotten rid of before printing because the first time when I had them, the laser cutter just moved rapidly without cutting anything...

Then Oscar trained me to use the electric screw driver:

It's very useful and you can use it to unscrew too.

But anyways, I eventually put together all the pieces:

Obviously, it's just two separate pieces. Although I think performance definitely improved in this design. The decision matrix for this one turns out to be:
Performance ++
Manufacture ++
Aesthetic + (because there is a big space left at the end of the split)

Then Oscar and I discovered that we can actually make three rectangular pieces with Kelsey's design:

That way two adjoined sides can bend in the middle so makes it a movable "spring" joint. My design for next class:

The middle part looks funky but I checked color and width of the strokes and they were all good... I guess I will have to figure it out when I go to class.

My expectation for the decision matrix of this design is:
Performance +++
Manufacture ++
Aesthetic +++

Hope that I will have time to figure something out when we come back from break.
