Step 1: Materials
Mini USB (not pictured)
Assorted legos from the picture above
Step 2: Construction
Step 3: Construction
Measure the size of your USB and use a multi funtion power tool to make the proper cut into the lego like the picture below. I used a mini USB that still had its plastic casing on it but it didnt fit all the way so I sanded some of the plastic on it until it fitted. Sorry for the picture below, I know its not very clear but I could not find a decent photo to illustrate the point.
Step 4: Construction
Step 5: Construction... Almost Done
Put a small amount in the hole that you cut out with the multi funtion power tool
To fill the gaps, I put some epoxy in a plastic baggy and cut a really small hole in it and filled in the spots that needed more epoxy
Step 6: Finishing Up
Let the glue dry completely before using
I dont know the long term problems (if any) from the superglue because I kept the casing on the USB so I doubt anything bad will happen from the fumes of the glue.
