After returning to the drawing board for what feels like the hundreth time I feel like I am about there with my design! It is tiny. So compact and small that you could fit in a tiny coin purse and still have room for your bus change.

I've made a few changes since I last drew my design. The design no logner has a cap. The usb will be cased in at the top and that will be it. This is because after speaking to people such as my sister and her friends who are all students they said they always just lose the lid anyway. This factor is also true to me, so I decided not to make one. If this product went into mass product this would also make the product cheaper to make.

So far my design is 35mm long, 20mm wide and just under 10mm in height. The is the smallest I could possibly make it to encase my usb board.
