Quadcopter: 3D Printed Leveling Workstand
I often mess around with my quad configuration. Sometimes I re-flash the firmware which requires the re-calibration of the accelerometer and magnetometer. To calibrating the accelerometer, the quad has to be on a level surface. I have a 4-in-1 Quattro ESC mounted to the bottom, which makes an excellent platform to mount to. After tinkering on TinkerCAD (see what I did there?) for a few minutes, a base was born. I also had a round bubble level laying around (got it at CDN Tire), which I mounted in the middle. Pics of the printed unit and quad mounted below.
