180mm Quadcopter Frame WIP V0.3 (UPDATED)

thingiverse

This is my latest iteration of my 3D printable quadcopter frame, designed with the objective of fitting within the Anet A8 build volume, thus making a 250 quad feasible only if I break it up into multiple components. The smallest size I can create for a quad with 5-inch props without them hitting is achieved here. If you're using a CC3D (it might work with other flight controllers as well), you can also download the transmitter holder from https://www.thingiverse.com/thing:2456194, which I recommend printing in TPU. However, I'm unsure how well a PLA-based frame would hold up. I'm considering printing this in PETG because I'm pretty sure it's a lot stiffer. PLEASE DON'T Print V0.2 as it's subpar, might work with PLA but I doubt it. What changed for V0.3? The thickness of the arms was increased and a chamfer was applied to them, resulting in a decreasing thickness profile from the body to the tip of the arm, which should increase stiffness. When printed with PETG, the stiffness and torsional stiffness were abysmal for V0.2, so I had to make some adjustments. Additionally, the position of the octagons in the arm was changed so they aren't as close to the edge of the arm.
