Watchband QR Code Accessory

Build Instructions:

• Orient print standing up like in the images above
• Requires a brim or raft
• Printed with 0.4mm nozzle

Post Build Instructions:

• Generate your QR code using whatever method you like
• Open a new file in your photo editor of choice (I used GIMP) and choose the US Letter template
• Import QR code into image and scale it down to 18mm. Duplicate QR code as many times as you think is reasonable on the page.
• Print image making sure margins are disabled
• Cut out QR code
• Place QR code face down on scrap of cardboard and coat the back with a gluestick
• Stick QR code on print and let it dry for at least 5 minutes
• Cover QR code with clear packing tape 
  • This is to improve water resistance.
• CAREFULLY use a sharp knife to score the edges of the tape just a little inside the face of the print
  • This produces a cleaner cut, makes it stick better, and keeps it from hanging off the edge where it could easily peal up. You do not have to cut the tape this way if you feel uncomfortable doing so. You can use scissors and try to cut as close to the edge as possible. Be careful if you choose to score it though, especially on the clip on variant (which is a little less wide). I am not responsible if you cut yourself.
• Peel away the tape
• ???
• Profit

Compatibility:

• This should work with most 18mm watch bands.
• This also works with 18mm nylon watch straps (the rainbow one) if you wish to use this without a watch.

Why I made this:

This is my first original print I made after buying my printer. I made this as an accessibility tool for my job as a Fulfillment Expert at Target. Our role requires us to go around picking items for guests who order online for drive-up, in store pickup, or to get the items shipped to their house. We do so by first scanning the product's barcode, and then scanning a label on our cart. 

It is fairly common practice for seasoned fulfillment experts (at least at my store) to have a custom cart location barcode on their name tag, especially to pick bulky orders which often require a flat (most of our flats do not have cart location labels at our store). Outside of bulky orders custom cart locations are also useful if you need to pick multiple items in an aisle but can't get your cart through.

This accessory is an alternative to having a cart location barcode on your nametag. It's more comfortable / ergonomic, and in my opinion is a little cleaner.
