Design a keyring that attaches to an iphone 5 docking.... (content notes hidden for buyer privacy)

We have created an electronic unit that transmits a wireless signal when turned on. We wish to enclose this electronic unit in a plastic box that incorporates an “activation mechanism” to turn on the electronic unit. The mechanism should be designed so that the electronic unit is quick and easy to deliberately turn on in a moment of panic. However, the design should also prevent against accidental turn on. Finally, when the mechanism is turned on, it should remain turned on until explicitly turned off. The electronic unit has the following dimensions: 28mm x 14mm x 6mm [length, width, height]. The enclosure for the electronic unit and activation mechanism must be as small as possible. We do NOT want a bulky box or bulky activation mechanism. It must be as small and sleek as possible. This electronic unit will have two wires that, when connected, turn the unit on. Thus, these leads should be connected when the mechanism is turned on, and otherwise remain unconnected when the mechanism is turned off. If you choose to use an electronic switch to handle this, please see the additional information paragraph. We want to 3D print this design using a ProJet. Please provide detailed images of your design, as well as the necessary CAD and LST files. Additional Information on powering the unit using electronic switch: If you wish to use an electronic switch to power/unpower the electronics in the mechanism, you may find the following source useful: http://www.omron.com/ecb/products/sw/. This manufacturer makes very small switches, with their smallest switch measuring only 3.5mm (ultra subminiature SMD switch: http://www.omron.com/ecb/products/search/?cat=2&did=1&prd=surface&lang=en). For your reference, these switches can be bought in two modes: Normally Open (NO), where the electronic unit is powered when the switch is being pushed down, and unpowered when the switch is not being pushed down. Normally Close (NC), where the electronic unit is powered when the switch is not being pushed, and unpowered when the switch is being pushed. You may find these modes of operation useful when creating the design. CAD files of these switches are available on Omron’s website. Of course, you may use switches from other manufacturers if they better fit your design needs.

The e-touch The e-touch is a smart bracelet that has to be synced to your mobile device, when entering an event, meeting or club. When the connection between your mobile device and the e-touch is made, you can go ahead and 'e-Shake'. How does it work? When entering an event you’ll receive an e-Touch bracelet. By shaking hands with other people wearing an e-Touch, the bracelets connect and sync information trough your handshake, called the ”e-Shake”. The information received trough e-Shaking will be sent to an app, called Shake-on, on your mobile device which will store the information on your phone. Depending on your app settings/preferences the new information/friendship will be published on your Shake-on account (your personal page on the Shake-on social website).

Modeling the head of people Printable 3D

I need a plastic prototype design in 3D. This object is a hollow ball (20mm in diameter, 1mm in thickness). The ball is composed of 2 parts (top and bottom piece). The top piece will slide into the bottom piece. On the top of the ball are small air vents (0.7mm) that form the shape of a circle. The bottom of the ball will have an opening (4mm diameter). There is a small arch inside the ball that sits at the base. The arch will extend from one end of the opening to the other. The arch will will be 1 mm in thickness. I have attached images I created with paint.
