Step 1: Things you need
Double Sided Adhesive Tape
Step 2: Create a hole for the charging port
Since I am using a micro USB port phone, the hole that I created on the card is around half an inch in length.
Step 3: Fold the base
After making the line where the card should be folded, heat the folded surface of the card with a lighter to make it more pliable and easier to fold. continue folding the card until the fold is around 135 degrees from the original position.
The end result should be a card that looks like a sled board with the hole just below the fold.
Step 4: Support assembly
Stick some double sided adhesive tape below the support assembly so that it can attach to the base.
