3D Printed Braiding Machine / How It Works, Construction, Technical Details

In this video I build a 3D printed braiding machine. The braiding machine was recreated from old photos, from the early days of braiding machines. The braiding machine works really great. So far I have created about 50m of cord without any problems. The output is 42cm per minute. A 24V DC gear motor drives the machine. 6 bobbin holders are used. A bit tricky was the device for tensioning the single cords. But this works perfectly now. If you change the gear ratio, it is also possible to produce cords with a core. All parts are easy to print. Supports are included in the 3D models. On Thingiverse and Prusarprinters I have made all parts, drawings and templates available for download. Have fun building.

Here you can see the basic assemblies.

The base plate was made of acrylic glass. The shape was printed on paper and glued. The parts are cut, sanded and drilled.

3D print the parts. All parts can be downloaded.

Here you can see the base plate with the gears. 6001-2RS ball bearings are used.

The shuttle is guided in the acrylic guide. The gears push the boat further and further.

This is the coil holder. A 12x1mm aluminum tube was used. The steel weights ensure the maintenance of tension in the cord. The spool holders circle each other, braiding the line.

The extraction speed is set via the gear ratio.

Be careful when threading the cord!

The rope production can start.

You can see more technical details in the video.
