Designed as fully universal (multi-fit) landing skids. They attach to the main body of the multi-rotor with a single bolt and have two small lugs to stop the legs twisting around. Feel free to cut off the small lugs if your application doesn't need them or drill more holes if required. (If drilling more holes, print the legs using at least 30% infill - 50% would be better. Height = 70mm, skid length = 155mm They are strong and very simple to print (refer to instructions below). Suitable for 450mm multi-rotors and below and are high enough to accommodate all batteries or a GoPro swivel camera mount. I looked all over Thingiverse but couldn't find any universal ones, so I hope you find these useful!Depending how strong you need them (remember, these are designed to break 'first' before damaging your multi-rotor body in a crash or very heavy landing (can easily be replaced!) Recommended print settings are: Filament - PLA 1.75mm Infill - 20% to 50% (depending on required strength - higher = stronger) Shells - 2 Layer Height - 0.20mm Temp - 230C Extrude Speed - 90mm/s Travel Speed - 150mm/s
