Learing openSCAD!

So i'm going to make the case of the mouse in openSCAD so i firstly need to learn it yeah so ive been learning from the official tutorial and in that tutorial you make i little car and i'm already getting the hand of openSCAD yeah ive been also just playing with openSCAD. Then for the PCB side ive done reserch on the sensor so i'm going to use a PAW33935 wihch is really performant and standard but the only thing that i dont know if i'm going to make the whole PCB because it might be too complicated
