Quadcopter arm Replacement

thingiverse

Quadcopter/Hexacopter arm replacement with round shape to reduce resistance for propeller. Designed for 2212 920KV and GF2215/20 motors. Also oval shape helps reduce bending and flipping of arm comparing with flat versions. quad_leg_2212 920KV_hole_for_wires_oval version is with added center oval hole 6x4x4 mm size. quad_leg_2212 920KV_9_20150111 - version with removed leg and increased resistance of bending in perpendicular direction according motor axis.(Problem is that: When motors with propeller are not balanced correctly there is bending vibrations in perpendicular axis vs. motor axis). Instructions Printed with Green ABS. Layer Height: 0.2 mm Nozzle Size: 0.3 mm Fill pattern: Rectilinear Fill Density: 30% Vertical Shells: 3 Horizontal shells Top/Bottom: 3 Total Weight: ~32 g. (Original Weight ~52 g. Dark Red 53 g.) Printed in 45 angle vs Z axis, because of small heatpad. Thus fill pattern generated with Slic3r is 45 degrees. quad_leg_2212 920KV_hole_for_wires_oval oval hole 6x4x4 mm size printed with green ABS total weight is 31.42 g. Printed with white PLA (30% infill) weight is 33.92 g. Arm printed with PLA seems more flexible than printed with ABS. It bends more easier. with 25% infill PLA arm weight is ~31.2 g. quad_leg_2212 920KV_5x8_wires_hole with larger oval hole for motor wires (Not printed yet). Weak place found ARM leg it can easy broken.. next versions will be with lower but thicker leg. quad_leg_2212 920KV_V201506 - this version is with reduced body thickness and strengthened leg (contact to arm - near motor). (not printed yet) quad_leg_2212 920KV_V201506 i printed with PLA 20% infill rate total weight is 29.79 g. and maintains similar strength comparing with older versions. Thus printed with ABS weight should be around 2-3 g. lower.
