Printable without support material—ready to produce on demand
Handles angular misalignment, offset shafts, and end float issues
Provides soft-start damping between connected shafts
Fully mechanical design for reliable shaft connections

This is a fully printable flexible coupling designed for workshop tools and mechanical assembly. It solves alignment challenges that rigid couplings cannot—accommodating angular misalignment, offset shafts, and vertical float while requiring no support material during printing.

The flexible design absorbs mechanical shock and provides a soft-start lag between connected shafts, reducing stress on motors and driven components. Ideal for DIY robotics, 3D printer upgrades, and custom machinery where precise alignment isn't always possible.

Print it as-is and use immediately. No post-processing or assembly jigs required.
