8mm Hex Shaft

A simple and practical 8mm hex shaft designed for use in robotics, mechanisms, and custom 3D-printed assemblies. The hexagonal profile provides a secure fit with compatible hubs, wheels, gears, sprockets, and other components while allowing reliable torque transfer without excessive slipping.

This shaft can be used for drivetrains, intakes, lifts, arms, slides, and other rotating mechanisms where an 8mm hex interface is required. It is especially useful for FTC and other educational robotics projects where custom mechanical parts often need to work alongside standard hex hardware.

The design is intended to be easy to print and integrate into your own mechanisms. Adjust the print settings and tolerances as needed depending on your printer, filament, and the fit you require.

Features:

• 8mm hexagonal shaft profile

• Designed for mechanical power and torque transfer

• Compatible with 8mm hex hubs and components

• Useful for robotics and custom mechanisms

• Suitable for prototyping and functional parts

• Easy to integrate into custom 3D-printed designs

Recommended material: PLA, PETG, or another suitable engineering filament depending on the load and application.

Use appropriate tolerances for your specific printer because, naturally, printers have decided that "8mm" is more of a philosophical suggestion than a measurement.
