RC Airplane Incidence Meter

It is an incidence meter used in model aircraft, initially I put a bearing on the arrow, but it wasn't very functional and what's best is to put a fishing weight tied to a thread in the area where the bearing should go, this way the level is perfect to measure the angle, in the end I named it ANGULÍMETRO. It doesn't need supports and a 0.20 layer is enough, with 15 percent infill is enough. I hope it is useful to you and measure the incidence of both the wings and the vertical tailplane.
