I got a cool USB3.0 flash drive as a prize from somewhere, but the casing was ugly and bulky so it got tossed into a drawer. I dug it out recently, realized I could just take the drive itself out of the casing and print a better one, and here we are today! I used FreeCad 0.17 to make it and learned about the shape binder tool in the process. I included the model of the flash drive I made. I used a tolerance of 10 thou for everything and it worked perfectly. Some hot glue will eliminate the slight wiggle.
