TWE210 Quadcopter Shark Fin and Antenna Mount

thingiverse

I'm sure many of us have built our own UAV futures $100 quad. We use the HSKRC TWE210 frame from banggood, which is an incredibly solid frame that has withstood many brutal impacts. However, I managed to break off the very back of the tail on the top plate with the antenna mount hole piece attached to it - you'll want to cut it off and file it down before using this if you haven't broken it yet, but this version is much better. This is a high-performance top fin designed to help with turtle mode, featuring an integrated stubby antenna mount. There are several channels in the bottom that allow zip ties to pass through for securing electronics and wires to the top plate as well. I printed this on my Ender 3 using a .12 resolution with TPU at a 30% infill gyroid pattern on Cura - don't hold me to the percentage, though! The current print is on Amazon TPU with a shore hardness of 80, which makes the fin very flexible yet still allows for a quick backflip into turtle mode to right itself. It can also be printed using a harder filament like sainsmart TPU.
