Axiom 250 Quadcopter

thingiverse

Axiom is a quadcopter focused on three things: Durability, safety, and modularity. The interlocking shroud design is safer to fly, easy to print and the 250 mm quad size works on most printers. If you are a STEM educator, Axiom would make a great project for your classroom. It teaches important concepts in physics, engineering, and even computer programming while engaging students in the exciting fields of drones and 3D printing. Instructions Instructions for printing and assembling Axiom can be found here. Recommended components 2206 2000kv brushless motors (4) 6x4.5 triple-blade props (2cw, 2ccw) 30 Amp ESC's (or use motors with built-in ESCs) (4) 1800 mAh 3S or 4S LiPo battery Pixracer, Naze32, or other 36mm flight controller FPV camera Video transmitter (most sizes can be used) Necessary hardware (screws, etc.) and printed parts for those without access to one can be purchased here. Hardware: Aluminum female-female hex standoff, M3 x 37, 4.5mm hex width (8) M3 x 8 button head cap screws (40) M3 nut (2) No. 2 thread-forming screws (4) Male-female nylon hex standoff, M3 x 10 (4) Female-female hex standoff, M3 x 12 (4) Zip tie, 4", narrow (8) Zip tie, 8" (2) Self-adhering Velcro strap, 280mm (1) 2mm hex driver (1) Print Settings Printer Brand: MakerGear Printer: M2 Rafts: No Supports: Yes Resolution: .2mm Infill: 30% Notes: The propeller shrouds are designed to fit on any printer bed which is at least 7.8" wide. This includes Makerbots, Ultimakers, the Prusa i3, and lots of others. Just remember to disable rafts, skirts, and brims which can increase the build footprint and it should fit easily. The recommended material for this design is ABS but PLA has also been used successfully. Just be careful about motor temperatures as they can reach levels that will soften the PLA enough to allow the motor screws to loosen. All STL files are oriented for optimal surface finish and minimal supports. Many of them can be printed with little or no support, so feel free to test your printer and experiment. This design prints well (and fast!) with oversize nozzles. You can use a 0.75mm nozzle with 0.4mm layer thickness and get great results. Standard size nozzles will work fine too though, and can create thinner walls for reduced weight.
