The next step is to create a 3D printed case for the PCB and the sensor. But to do this i first created a 3D model of the hole assambly to thest everything first. And as it turns out it really was a good idea:

As you can see i forgot the mounting holes in the PCB...

For the 3D software i use SolidEdge as i learnd how to use it in shool and is aviable for free for students.
