thingiverse

Properties: z = 150, step = 0,5mm Fully functional part. Complete part: HK450_main_gear_complete.stl 2 parts: HK450_main_gear.stl + HK450_main_gear_axis.stl (This way you only have to replace the gear when a tooth is broken) Instructions Printer setup: Layer height: 0.15mm Print speed: 15 mm/s Printed in PLA and flight tested, an ABS print must outcome an stronger part for this applicaton. Update: I have realised that the PLA is great for avoid damage in helicopter crashes (I have had several last days ;) ). PLA main gears acts as a mechanical fuse better than standard gear (ABS), in a crash teeth break apart quickly and avoid damage to other parts of the rotor
