Busy days, way to busy to even think about this project. Ive found some time to design next version of the air speed indicator. Bad luck, yesterday I've lost 4 hours of my work due a crash of Fusion 360 :/ Cant blame Autodesk, its still very early version of this software. As a software engineer I entirely understand that this can happen. So designed it again, here's the result. 3D printing tomorrow.
