This is the v1 of a Mega drone frame, fully 3D printable that can be assembled as a bi-copter, Quad-copter, Hexa-copter, and add a new feature below. What I call "Gripper-Legs", because well, they act as a gripper and as the landing legs*. (Now don't pay much attention to the gripper-legs on the STL as this feature was imported from an external file and not designed by myself).
*Well, this may be confusing. The drone can land on its own arms, as they are meant for that purpose too, but this gripper feature (also 3D printable) is for a bigger project of a convertible flying drone capable of carrying goods. Such as packages and more.
And to make it easier and reliable, I designed the legs so you can do both functions on them if you program them to do so. Landing and gripping.
Now for this project you will need some M4 screws and nuts. To connect the arms for the rotors, you will need 2, 4 or 6 (depending on your build) M4-12(long) allen (in mm). and to attach the other main bodies, special M4-50(long) allen (in mm).
The reason of leaving enough distance in between the core parts is because you will have around 3-3.5 cm height to insert Flight controller and ESC, or battery, or any other board you may want to + the servo motor battery and cables in case you go all in.
This project is still ongoing and if you'd love to help me create and develop it you can do so by contacting me by e-mail (maiktcp@hotmail.com).
