Hahaha, yeah, I know. With the 3D case, make sure that the bottom is not lower than the nozzles, or the case will either drag in the powder, or the distance of the jets to the powder will be too far.
I did receive my clean head today, so I can start testing a little bit more. The PCB had a technical error, so the circuit board maker is a day behind. It usually takes 5 days depending if they can fill the board.
