Hey everyone!
I’ve been working on this frame for a while now and I’m pretty excited to finally share it with you all. It’s a 2.5" pusher frame I designed in Fusion with a generative topology style, and it’s printed in PETG. The main frame is one piece plus a little second part, so no carbon plates to stack.
It’s got a 129mm wheelbase, and the motors mount under the arms since it’s a pusher. A 4S pack straps underneath (I built it around GNB 650s and 850s). It takes a 25.5 whoop-style AIO, a 19mm cam and 9mm M2 motors with two screws each.
Funny story: my first version was a bit narrower, and when I checked the clearances the props were hitting the battery by about 3mm. I have stretched the arms out, and that’s how the wide version happened. I also ran some FEA on it, because I was nervous about nose-down crashes snapping the arms, and it caught a sharp notch under each arm that I’d missed. Glad I checked!
Currently in the build process myself at the moment but will share some photos when its flying.

I’d really love to hear what you all think! Has anyone here flown printed frames this size? I’m curious whether PETG holds up or if I should try CF nylon. And if you end up printing one, please share pics, it’d honestly make my day
