I have a USB memory stick with built in security software, GREAT! However it tends to be a little unreliable when it comes to using the memory stick on computers other than my own either taking ages to get logged into it or even not getting access to it at all.
So i decided that after receiving a free 3D print from the last competition i decided i would design a combination locked USB memory stick using Solidworks 3D!! Which should be here any day?
Using 4 wheels numbered 0 - 9 gives me 10,000 Combinations!!!!!!
Here are the results and i hope you enjoy the step by step guide
Step 1: USB Memory
I started off by measuring the usb with a set of calipers and making a sketch of the PCB on the top plane and extruding it to the appropriate depth.
Next on the right plane i sketched the metal part of the USB (male End) extruding it also.
With the USB completed in one part i could now use it to design my casing around!!
