Launch pad for (DJI) drones - total size 300x300mm

Hello my friends,

I'm pretty new in flying with a drone and I have a DJI Flip Drone at home.

I like it so much. I made a lauchpad for you. Not only for the Flip Drone. ;-)

It has a total size of 300 x 300mm and comes with 4 bases and some connectors.

Fell free to glue all parts together. 

I used the  the oktagramm pattern for it but you also can used any other pattern, too.
