I just bought four rolls of duct tape, and needed something to do with it. My little brother was bugging my dad for a new 3DS case, so a little light bulb went off in my head, and I got right to work! Average time: 45 min - 1 hr.
Step 1: Materials
You will need
• A primary duct tape color (referred to here on in as Tape A)
• A secondary duct tape color (referred to here on in as Tape B)
• Console, games and in this case, a stylus.
• Pen and paper
• Velcro dots (2 is enough)
• OPTIONAL: Something to cut the tape with. I used my hands and found it to be easier.
Step 2: Take some measurements
Make some measurements of whatever you need to hold. Try to keep it wider rather than thinner, so there's a little wiggle room. The stylus is not as important, as we will only make a small holster/slot for it.
Use enough of Tape A to cover avout 2.5x the length (top to bottom) of the console, and make a sort of "cloth." Five pieces was enough for me. Don't worry about the ends not being perfect, we'll cover those up later. Place more tape on the cloth, sticky side to sticky side, to make a duct tape cloth, so to speak. Then, fold lengths of Tape B over the sides to A) cover up the ragged edges and B) to make it look cool. It should loosely hold the console folded over, with plenty of overhang.
Step 4: Make game slots
Make a small piece of duct tape loosely the dimensions of the game, with about the width of two pennies on any side. Then, use a larger piece to cover it. There should be a "U" shape of stickiness around a "cloth" portion. Stick that on the case, with the open end at the top. Continue until you reach the desired number of slots. My brother wanted six, so I made six slots in a 3x2 rectangle.
