75mm 3D-Printed Prestress FPV Frame
Print Profile(6)
Description
Update:
Add optimized v2 frame print profile
- Adjusted motor screw hole for precise fit.
- Adjusted battery slot.
- Structural changes.
- Add m2 stack screw mount (recommended). Now 2 layer stack is available.
- Add a thicker version for softer filament. (use m1.4*4 motor screw)
- Add optional TPU canopy.
Frame noise profile: default Air75 tuning, with old noisy props.
I have been trying to make 3D printed FPV frame that can fly well. Check my previous design. This is a new ultra light 75mm toothpick frame with prestressed structure, aiming for light weight, noise control and easy build.
The frame include 3 parts: lower plate, upper plate and FC mount. Only hardware other than printed parts: 4 motor screws(m1.4*3/m1.4*4). Theoretically usual 75mm tiny whoop electronics can be moved to this frame.
I moved my Betafpv Air75 to this frame and tested it. It's too cold outside so I only flied 4 packs. So far this frame feels good, better than the Air75 whoop frame (a bit too soft for me). Further optimization working in progress.
