The trick of this stand is that it uses the device's own weight to prevent itself from toppling over - just like a bookend.
Level : Easy
Cost : $0 (approx.)
Time : 2 min
I have also discovered that if you use two of these paper clip stands you can easily support a Tablet in landscape mode.
There is also a video to this and if you want you can jump directly to the last step to go to the video.
Step 1: Materials Needed
1. A paper clip (obviously)
2. A pair of pliers or something similar to bend the paper clip.
Step 2: Observe & Bend : Observe the Clip & Bend It to Your Will
The first step is to pull these two in the opposite direction. Push the smaller bend downwards in such a fashion that its curve is pushed down. At the same time push the larger bend upwards. Pull the two curves apart so that they are around 90 degree apart.
The smaller bend, the one with the small curve, would act as the 'Base' of the stand and the larger bend would act as the 'Back' of the stand. The phone would rest on the base and the stand.
Step 3: Make the Clip Stand on Its Own
The end result here should be something like that shown in the third image.
Step 4: Use the Pliers
Using the pliers hold the smaller bend of the clip at its 'curve' and then push that upwards. The end result should look something like that in the image. The bend is made so that the phone does not skid off the stand.
This is your stand. Try it out. Make any adjustments as per your requirements.
If you are going to use this to hold a Tablet or the now in vogue Phablets or you determine that you would use two of these together then do take care that the angles between the two bends is similar in both the stands.
