This is a remix of the "DIY Multirotor Parachute System" by AverageguyRC http://www.thingiverse.com/thing:796612

I used his original parts design as a starting point but made the parts so they can be printed in PLA and I shaved off a lot of the extra bulk and weight that was needed with the original design for it to be able to printed in abs and still be strong enough. This new design if printed in PLA can be printed with an infill of just 5% and the parts still come out strong yet almost 60% reduction in weight.

For more info on this system and how to put it all together see the links on the original page for the "DIY Multirotor Parachute System" by AverageguyRC
