In my eyes, the included four T6 screws make the assembly of AirGradient Open Air unnecessarily difficult: They are too long, whereas the screw driver’s handle is too small to put enough power to them to nevertheless make the encasing’s top and bottom parts be really safely fixed to each other.
The alternative shorter screws from a former video are no more included, and the soap mentioned in a later video may be only an emergency solution (I didn’t try).
I helped myself by using M2x10 mm screws. This size really works fine.
Additionally, now also the two shorter T6 screws for fixing the PCB are slightly too long after the formerly included plastic washers are missing currently. In this case, I added two metal washers myself which solved the problem.
Maybe the screws included to the kit could be optimized to reduce trouble.
