Here are the specific mounting options for this assembly: Human uses M3 fasteners for every application except motor mounts. Assembly requires either a monocoque base plate or separate arm pieces. If you're using a monocoque frame, make sure you have 10mm M3 screws on hand to secure it. Separate pieces need ~16mm M3 screws that will allow them to expand enough to provide the required space. This product also features mounting holes designed specifically for the Naze32 system. I highly recommend using 38mm aluminium spacers as an essential addition. For successful printing, I suggest you use a ABS material with at least 10% infill. To ensure maximum stability and durability, go for 15 to 20% instead.
