Introduction: Lego USB Flash Drive Bracelet

I have seen a number USB flash drives bracelets around and really liked the idea. It seems like a convenient way to keep a  flash drive handy, though it does seem a bit geeky.  Now I am not one to shy away from my inner geek, rather I figured I would take it to another level and make a Lego flash drive bracelet.

Step 1: What You Will Need

  • USB flash drive
  • cord, string or elastic
  • LEGO  (eight 2x2 and one 2x4) you may need more or less depending on size of wrist
  • Sugru
  • Glue
  • Rotary tool

Step 2: Prepare Lego and Flash Drive

  • Carefully remove the case of the flash drive, it can usually be pried apart without too much trouble.
  • Drill two holes on opposite sides of the 2x2 pieces with a 1/16th drill bit.  I did this to all but one of the 2x2 pieces. The holes should line up, marking the spot with a pen before drilling will help.
  • For the last 2x2 piece removed the tube from the underside of the piece and one wall.  On the opposite wall, I drilled two holes (see above point), this will be the cap.
  • For the 2x4 piece, removed the three tubes on the underside. Remove one wall and drilled two holes on the opposite wall (same as above).  I needed to grind away a bit of the inside with my Dremel to get the flash drive to fit. 

Step 3: String Your Lego

I measured the size of my wrists to determine how many Lego pieces I would need.  It should fit loosely to be comfortable (you don't want little Lego square impressions on your arm).  I used a shoelace as the cord to connect the pieces (the gathered ends made it easy to string through the holes in the Lego).  I started at the one end, looped back and tied a knot.  I reinforced the knot with super glue to prevent it from unravelling.  Make sure the 2x4 piece and the 2x2 cap are on opposite ends.

Step 4: Add Flash Drive

Now it is time to insert the flash drive.  Blue Sugru is conveniently similar to the colour of blue Lego, which is part of the reason why I went with the colours I did ( and it is my favourite colour).  To centre the flash drive in the brick,  I added a layer of Sugru to the bottom of the 2x4 brick, added the flash drive and covered the rest of the brick with Sugru.  I had enough Sugru left over for the cap.  First I covered the USB end of the drive with plastic wrap (to prevent the Sugru from sticking).  I pressed the Sugru into the cap (the 2x2 piece), inserted the USB end and covered the rest of the brick with the Sugru.  While it cured, I used a 2x4 piece to connect the two pieces to make sure that the flash drive remains centred.
