I wanted a stand for my phone, but I needed to be able to carry it around with me. The ideal size was a credit card. So it seemed obvious to make it out of one. Or rather, two.
Step 1: Find Some Credit Cards
Take 2 credit cards. These are for some lottery I think. They were giving them away at the corner shop. The standard card size is around 85.5mm by 54mm.
Step 2: Trim One Card
Cut a 12mm strip off the edge of one of them.
Step 3: Join the Cards
Using sticky tape, stick the edges of the 2 cards together to make a hinge. Fold back the other way and stick the other side too.
Step 4: Trim the Join
Trim the excess tape off. You should now have a hinged pair of cards.
Step 5: Add Brace
Cut a 45mm wide strip of paper. Tape this in the same way onto the card edge you cut earlier.
Step 6: Join Brace End
Tape the other end to the intact card, 12mm from its edge.
Step 7: Tidy the Frame
Fold the cards in two and trim off any excess paper and tape. This will also fold the paper in two. You now have the frame of the stand completed.
Step 8: Add Friction Strip
Take a thin strip of rubber. This is from an old bicycle tyre, but I expect an elastic band will do just as well. Glue it, using a suitable glue, to the edge of the card, just a couple of mm should do. It is to hold the edge of the phone and stop it from slipping off the stand.
Step 9: Trim Excess
Wait until it is dry and cut the excess off with a pair of scissors.
Step 10: Done
Finished! You now have a mobile phone stand that fits in your wallet. If you prefer a different angle you can change the width of the strip of paper to suit.
