Step 4: Glue and insert flash drives

Picture of Glue and insert flash drives
Now it's just a matter of applying glue, I used Elmer's® Carpenter's® Wood Glue, clamping it and letting it dry.

The fit was so snug that I just pushed the drives in and they're staying put. If it's a little loose you can easily dab a bit of hot glue onto the end and the sides of the drives and use that to keep it in place.

So now you have a double-ended flash drive. Carry your digital life around with you and take on everything.
