School Project DIY Quadcopter

thingiverse

A simple Quadcopter frame designed for a school project. We planned to 3D print everything, but due to a lack of time we had to resort to a laser cutter for most parts. Obj's are 3D printed, svg's are lasercut from 4mm plywood. Arm heads designed for NTM Prop Drive 28-30S 800KV / 300W Brushless Motor with NTM Prop Drive 28 Series Accessory Pack, and 10 inch rotors. Motors and rotors might be a bit overkill, but we overestimated the total weight (we might be able to contest in the Hobbyking Beerlift now :D). Instructions 3D print the Inner top plate once and the armhead 4 times. Lasercut all the svg's in 4mm plywood (We did the 2Legs.svg twice, the bottom plate is made for 2 times 2 legs, but just 2 will work fine) Get yourself 8 4m50 bolts with 4 nuts per bolt, and 2 4m16 bolts (not necessarily 4m16, they can be a bit shorter or longer I think) with 2 nuts each. (Total 4mm nuts is 36) Connect the bottom and inner bottom with the 4m10m bolts, one nut between the plates, and one at the end. Lock the armheads into the arms using the indentations (maybe glue them together or tie them with a fishing wire or something). Attach the arms to the bottom plate through the indentation of the inner bottom plate with the armheads up. Put the 8 4m50 bolts through the 8 holes of the top plate, and use 8 nuts to secure the inner top plate to the top plate. Put another nut on each bolt for later. Line 8 nuts between the two bottom plates up with the 8 holes. Attach the top plates to the arms bolts down. Secure the bottom plates with 8 more nuts at the bottom. This was a stupid order of assembly, but the easiest way to explain in words, you probably know a better way yourself, but it got the point across. The order of plates, nuts and bolts should be: Bolt, top plate, bottom plate, nut, (arms clamped in between), nut, inner bottom plate, nut, bottom plate, nut. As for electronical parts, we are using an Arduino mega, 5000mah battery, the motors mentioned earlier and more good stuff. If you're interested comment or something, I'll try to help out.
