Mini/Micro FPV Quad

thingiverse

This is a robust little FPV quad I designed for parts I wanted to reuse. I aimed to create something that was significantly more durable than other options, but not excessively heavy. And this is the result - it's very durable and flies exceptionally well. This quad can definitely withstand some rough handling, but it's not invincible. It's one of my first attempts at modeling, and I'm thrilled with how it turned out! That being said, I'm more than open to any suggestions or requests anyone may have. Some important notes: The standoffs should fit snugly into place, depending on your printer's calibration. However, I recommend applying a small dab of hot glue to each end for extra security. I used too much glue in the photos. The camera will need some sort of mounting component - I just used hot glue. You don't need as much glue as I did; it got out of hand quickly on my model. I secured the motors with heat-shrink tubing, which ensures they stay in place during flight. The feet haven't been thoroughly tested, but they're designed to be disposable and protect the motor wires under the arms. They slide along the arm but don't fall off - they just snap onto the arm and do their job. My flight controller is held in place by foam tape, as is my VTX and Rx (above my FC). The longer end of the standoff goes into the lower plate. Specs: Made to house a flight controller up to 34x34mm. Designed to hold 8.5x20mm brushed motors snugly. Total footprint: 71x112mm. Lower to upper plate: 16mm. Camera mount to upper plate: about 14mm between closest edges. Top plate: 64x40mm. As I mentioned, I'm open to any suggestions or requests, and will do my best to answer any questions you have. If you want to know anything about my build or the hobby itself, I'll provide info on my quad and try to answer your question. Note: The completed quad in the photos is an older version than the empty frame or the files supplied. I've since added a place for a rubber band to strap the battery in and made some minor tweaks. Ignore the dirty work table. Print settings: Printer brand: PowerSpec Printer: PowerSpec 3D Pro Rafts: Doesn't matter. Supports: No. Resolution: 0.15 to 0.20. Notes: I use rafts when printing standoffs, which ensures they stay in place and are easy to snap off. Lower plate: 0.15-0.2 res., 20-80% infill (I usually go 0.15, 50%, but I haven't tested the pros and cons of other settings). Upper plate: 0.15-0.2 res., 10% infill or up (I usually go 0.15, 15%. This is just what has worked for me). Standoffs: 0.2 res., 20% infill or up (I usually go somewhere between 70-90%, probably overkill). Feet: 0.2 res., anywhere below 15% infill. How I designed this: Fusion360 I designed my first version in about 2-3 days of minimal work while learning the software. It could have easily been completed much sooner, but as said, I was still learning. And now I definitely recommend Fusion360 to anyone and everyone who wants to start modeling. It can do so much more than 123d Design (which I had been using) and is much less intimidating than Blender 3D.
