thingiverse

The X-Calibur is one of the fastest fully 3D printed quadcopters on Thingiverse, boasting a 250mm to 280mm diameter and top-notch speed performance. Engineered with speed in mind, this modular platform can be customized quickly and easily using minimal print material and weight. The result is a highly adaptable design that lets racers swiftly create and print their own modules to suit their unique needs. Plus, the X-Calibur can be printed on small 4.4 x 4.3" printers like the M3D with ease. To assemble this speed demon, you'll need eight bolts found at Home Depot or Lowes that fit snugly into 4mm holes and measure over 45mm in length. The modular plates have undergone rigorous testing for various components: Motor mounts: EMAX 2300kv proved to be a top performer Flight controller/receiver combos: Hobbyking's tx/rx and Naze32 both delivered excellent results Video transmitter mounts: Eachine ET200 showed impressive stability Camera mounts: Eachine 700TVL captured high-quality footage Arms: 6" props provided smooth flight, while 5" props offered agility Base plates: The MK KK power distribution board ensured reliable power flow Battery mounts: Venom 2200mAh batteries powered the X-Calibur with ease For optimal results, racers should print arms at a temperature of 75% or higher and use Polymax or PETG for arms and base plates. Other components can be printed using any filament.
