ATTENTION! This is both Instructable AND a challenge. You can be one of five winners of $100 worth of 3D printing credit from the nice folks at 3Dcreationsystems.com. All you have to do is make your own 3D design for a custom flash drive case and share a picture of the design in a comment below.
If you don't know anything about designing in 3D, don't worry! A template for the flash drive is at tinkercad. All you need to do is create a new account (easy), duplicate the template (still easy), and modify it (way easier than it sounds). And if you want to use your own favorite CAD program and make your own case from scratch that's also fine.
OK then, let's get started.
Step 1: Measuring
Here we get a height and width of 4.54 mm and 12.26 mm. This isn't too far off of the USB standards so that's good. It also has a length of 39.11 mm. Since flash drives need at least 12 mm at the end to go into the USB port, that gives us the dimensions 27 mm x 12.25 mm x 4.5 mm. Numbers slightly rounded off there.
