Flexible Landing Gear for Quadcopter "Crossfire" [deprecated]

thingiverse

Introducing an improved version of the landing gears for MikeyB's quadcopter "Crossfire". After experiencing a broken foot during the first test flight, these new landing gears are designed to be flexible and robust. They can withstand drops from about 30cm without issue, possibly even higher (untested). The unique feature of these landing gears is that they attach to the bottom plate using the existing screws instead of the arms. Additionally, the nut holders on the landing gears make it easy to retighten the screws between flights. At 30% infill, the added weight is approximately 50 grams. Note that adjustments may be necessary depending on screw length, nut size, and print settings to ensure a tight fit without damaging layers. To print, use only one object at a time and test for any necessary fine-tuning. Printing recommendations include layer heights of 0.2-0.3mm, infill rates of 30-50%, and 1-2 extra shells (equivalent to 2 or 3 diameters). No raft or support is required for printers capable of handling 45-degree overhangs. Ensure the nut holder area remains rigid during printing. For assembly, attach the top plate, arms, bottom plate, and landing gears using screws (M3 to M5, designed for M4, metal recommended) and nylon nuts in the nut holders. The screw can be tightened without holding the nut, as it will automatically stay in place. While over-tightening may cause layers to crack on the outside, the quadcopter should still remain structurally sound between the two screws.
