I've remixed the great landing gear for the Spidex Micro quadcopter by malopezn, this remix adds more tension to the arms that really keeps things in place, so good that I had my runaway Spidex free fall 150m onto a roof and this landing gear survived and was still in place, mind you nothing else was. There are two versions, one fits the original Spidex Mico Quad base, the other is for the remixed version that has higher support on the frame. There are two version, so make sure you print the right one. I print mine in ABS with 20% fill @ 0.3mm height
