This is a fully 3D-printed thrust stand I designed for testing larger RC motors, including 50xx-size outrunners. It’s built strong enough to handle serious torque without flexing, and it can be printed on any basic FDM printer.
Materials & Hardware
- 6 mm carbon-fiber rod for the axle/pivot.
- 7 mm carbon-fiber rod or CF arrow shafts inside the printed arms for internal reinforcement.
- CA, epoxy, or superglue works fine for bonding the printed parts to the carbon rods.
- 4 mm hardware is used for securing the motor mount to the frame.
- M3 screws are used to mount the motor itself. I’ll add more motor-plate variations sized for other motors later.
Print Settings
- Wall count: 4 or more
- Infill: 35%, set to cubic
- Layer height: 0.24 mm
- Filament: I use eSUN PETG because it’s tougher than PLA, handles heat and vibration better, and is still easy to print.
