[Wireless Room Temperature Monitoring System] Sensor Enclosure Prototyping Part 1

I have been doing some thinking on the enclosure i want to 3D Print myself.

The goal is to have a relatively simple design to store all modules : Arduino, Temperature sensor, 9V Battery enclosure and TX RF 433 Mhz Module.

Here are the first prototype drawings :

 

I am already having second thoughts about the enclosure, specifically about the antenna. My latest test showed that i should have a linear antenna instead of a coiled one...

I will have some more drawing done in the following days.
