Combination Lock USB Memory Stick
Intro: Combination Lock USB Memory Stick
The Problem:
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.
The Solution:
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!!
STEP 2: USB Circuit Board (PCB) Casing.
The catches/location points for the combination wheels were refined in the assembly at a later point!!
STEP 3: Recieving End of the Casing Combination Wheels
With this completed i could draw the edn cap for it which would keep the combination wheels on and in place.
The next part to draw was the combination wheel.

Also, the issue of cracking it with tension is important as well. Some way to lock the discs when tension is applied would do quite well.
However, this is certainly a novel concept. If it were a bit more secure (and reasonably-priced), I know of people who would buy it.

If you flattened the underside leaving just the top two thirds or so of the cylinder it would still lock into the combination part, but would no longer have this issue.

But I agree, well done, but let's see it when it's printed. ;)

I'd made onde nor in 3D printer ,but is a lot of piece of PVC tube, in another Intructables (I can't remenber).But It's work well

Ussually in a combination lock, the border facing the other part is put in place with fastener (bold, solder, or the ring is actually a nut with a looking bar).
