Quadcopter Launch Pad

This is a redesign of a Launchpad I found on Thingiverse, (https://www.thingiverse.com/thing:2393056) the original had the issue that the arms would slide down over time, so I added some knobs to prevent this. Downside is you can only change the angle in 15° Steps.

You will need 2x M4 screws + 2x winged nuts for the arms and one M3 screw to combine the two foots. The screw should turn freely in the foot, but should be fixed in the arm.

Since the knobs are really small, I recommend printing
