This is my design of a 3D printed racing drone, i tried to make it as durable as possible and still keep it light. The building part should be pretty straight forward for everyone who has put a drone together before, for all who never made one before you will find plenty of tutorials on youtube this one is basically the same.
Try to keep the cables from the motors and the esc's as low as possible, it makes the cable managment a lot easier.
You need M3 srews in the lenght of 26mm, 16mm,M3 washers, M3 nuts and some zip ties.
For the batterie mount i used some elastic band but velcro works the same, you can mount it on the top or on the bottom of the drone.
