a cardboard box for shipping or storing objects. i used it to store a 18650 lithium battery but the measurement can be adjusted to fit other things.
Step 1: Drawing the Case
measure the size of the object then draw it onto the cardboard with a little extra space. I have drawn a basic box design already the size will have to be adjusted
Step 2: Fold and Glue
cut a small groove into the lines for easy folding. Then hot glue ends to height.
Step 3: Hole
cut a hole where you want the flap to go
Step 4: Optional
if it is small wrap it in electrical tape.
