After designing the mechanism, it was time to model the main housing for the product.. The basic shape was going to be fairly straight forward as we had to have a small ring at the top for the flame dial and a larger ring at the bottom for the mechanism. Through our previous research into the lighting distances for lighters, we were able to determine the distance required for the gas outputs to be apart (hence finding the diameter of the output holes.. as well as finding the diameter to house the mechanism through the previous model research and simulations.

| Render: Mechanism in housing. |
The above image shows the initial housing model that easily houses the mechanism while tapering up towards the flame dial for the output of the ring of flames.

| Render: Initial housing with flame dial. |
The image above shows the housing with the flame dial above. The flame dial's size is set because of the gas line outputs but there may be room for the housing to change depending on gas storage requirements.
 |
| Render: Housing rounded to give warmer, welcoming appeal. |
This image shows how the base can run smoothly into the housing then into the flame dial - the housing needs to be made somewhat thicker to allow for the mechanism to screw into the side walls without protruding through the housing wall.

| Render: Gas release concept with OTS servo and circuit board in base. |
The gas storage concept shows how a distribution ring can be manufactured to be placed on top of the tank. however this will change as the ring is unnecessary and the distribution can be built into the take itself.

The servo motor arm needed to be adjusted several times to suit the diameters required to "knock-on" and "knock-off" the gas release mechanism. Space is being saved by mounting the servo motor directly on top of the PCB that will be used to control the product, using the same M3 x 5mm screws.
