Introduction: Paper Laminate IPhone Stand

I have previously done a few projects incorporating wood lamination, and one day whilst at home I decided to try out the technique with paper and other easily acquired items - it worked! So then I decided to actually make something useful so I settled on a simplistic iPhone stand as this could incorporate easy curves and edges.

Step 1: Materials

All you need for this is some normal A4 printing paper - I used white because that's all I could find.
You will also need:
-Scissors
-Glue (glue stick will work)
-CD (or something the same thickness as the phone)
-Wine cork (or a thick pen)

Step 2: Cut the Paper!

Title says it all really - just cut the paper into approximately 30mm strips, cut enough strips so that when they are all stacked and squeezed together they make up about 3mm thick.

Then glue them all together - yes it takes time but do it properly to get the best results!

Step 3: Moulding

Now to mould the laminates....
Start by bending it around a CD case to form the area where the phone will sit, and then bend the remainder around a wine bottle cork - a profile view of it should look a bit like a '5'.

Step 4: All the Trimmings

Let the whole thing dry, shouldn't take too long as it is only glue stick glue....
Then use scissors or stronger shearers to cut the whole thing down to size, and leave on a radiator to fully dry out.

Step 5: Finished!

Tah-dah! It should theoretically work because mine did... Anyway please comment and show me your experiments with this technique, and be kind - this is my first instructable!

Hello Flavrt,
I'm not sure if I fully understand the question, but I would personally keep the full span sheets on the bottom side of the design, as when someone sleeps on the top they are likely to sleep in the centre of the bed and henceforth where the slates are not - so this side would need the most strength to sustain rigidity and using multiple pices of plywood would increase the number of pieces of timber taking the strain, whereas if you used full sheets on top there would only be a couple of sheets supporting the body with no slates to support it. Also the multiple pieces of plywood could have different tensile strengths, so whilst one piece may support a load from 1 direction well another may support weight better from a different direction, so if lots of pieces are placed on top then it is likely that the overall layer will provide better support and this is important due to the fact that this is the side directly under pressure from a persons weight.

Good. Simply responding to such a challenge puts you well ahead of your piers. You also seem to have an instinct for structural analysis. Yes when in doubt, design for the load concentrated in the center. It causes twice the stress there than a similar load evenly distributed across the span. Continuing with your mathematics, you will be able to derive these point loading relationships from very simply formulas.

Here are some words to clarify the explanation. Whenever you build a laminate, you create a beam where all the pieces work together. The outer layers contribute the most strength to the structure. Layers applied toward the load are put into compression. Layers away from the load go into tension as the beam begins to deflect. So the underside of the bed is where continuous wood fibers are needed to resist tension. Scrap pieces can be butted together on the top, because deflection will simply push them together more tightly. Reversing the assembly, a functional beam would not be created because the layers would deflect independently — a house divided. The plane through the middle of the beam is neutral, contributing nothing to the structure — a good place for air.

As your laminations become more sophisticated, you will develop an appreciation for free air space in the centers. This is why I favor polyisocyanurate foam board. By itself a hopelessly fragile plastic, but laminated with foil, it develops astonishing stiffness. I built this lamination for its thermal properties. The walls are 6 cm thick and the whole assembly weighs less than 1 kg. It's 96% air, which insulates my food very well. Yet it would support tons because all the pieces work together as a beam.

((It gets very hot here in Sarasota.))

Well done and well said, young engineer. I hope your laminate crafting leads you further into the calculus of differentials and material science, so you can more deeply appreciate their inherent beauty.

Let me offer you this on practicality: Lamination is useful because it creates value. Regardless of the material, thin material like paper and foil is cheap and has weak properties. Laminating them into 3-dimensional structures increases those properties exponentially, for which people will gladly pay a premium.

Here is one of my stories. I had 2 twin beds, but really needed a bed 60 inches wide. So I was curious to see if the material from the twins could be reused. Lamination made the project possible.

I cut the bed slates in half, precisely spaced them to the new bed size. Then sandwiched them with screws between sheets of plywood. Despite the gap between the slats and a 40% increase in span, the resulting platform was stiffer.

Now here is a question to sharpen your thinking. It took all of 2 sheets, but they had to be cut into pieces to fit the bed. As the designer of this project looking for the most strength and economical use of plywood, which side (top or bottom) would you install full span sheets, and which would have the scraps?

Beautiful creative work. I have tried to design the same for my phone and after making two attempts i am successfully get one.
