Repeater Node - Heat Testing

The team deemed it necessary to heat test the 3d printed casing on the back of our repeater nodes. Given a number of these will likely be placed on rooftops and in direct sunlight, testing the integrity of the node under high temps for an extended duration seemed sensible.

Testing Environment

Above is the simple testing environment we used - a domestic oven with external thermometer. The node was placed in a configuration it would likely be mounted in, and placed in the oven at approximately 70 degrees Celsius for 2 hours.

As above, the 3D printed case is glued to the rest of the module - likely necessary to limit warping.

After around 2 hours at 70 degrees Celsius, the 3D printed case presented notably more malleable that at room temperature, however it did not warp or compromise it's waterproof seal in any way - likely from being secured to the rest of the module. The results indicated this case would be suitable for deployment, with warning to ensure it is not placed in extremely high temperature locations (if possible). Future iterations of the node could look at 3D forming methods which produce heat resistance products.
