Markqv Collapsible Bungee Tow Hook for 10mm Tube

Well this is an exact copy of Markqv's design, but longer and bigger to fit 10mm alu tube because it's more easily available at my place, and since i mount this for my big XUAV Clouds, probably better to be bigger.

Prepare a 37mm long 10mm outer diameter alu tube, slot it into the mount, align it, drill a 3mm hole, put your M3 screw through, then start trimming the excess with a saw or dremel. Picture attached for reference.

The M3 should should fit just the right length with your nut, apply some loctite.
