*This is a untested prototype.* I Found a handful of neat frames for this copter online. Had the idea to print them using Taulman 910 Alloy, which is really durable. Designs I printed seemed to lack rigidity. Design goals were to increase rigidity and trim some weight. Printed with Taulman 910 Alloy, 40% infill, tweaked solid infill threshold to 125mm^2, so arms are nearly entirely solid. Frame weighs in ~14 grams. Failed on the latter part of goal. Might have fallen victim to eye-candy over utility design principles. However, frame is extremely rigid. Integrated notches on bottom of frame to utilize attaching battery with bracelet loom bands. An idea borrowed from "Micro quad v1 remix for Hubsan X4" by mouserunner. Rotary slot pattern should accommodate Hubsan FC, as frame design is symmetrical, FC can be mounted facing either axis. Slot standoffs on top are meant as support material while bridging and designed to be trimmed off. *This is a untested prototype.*
