Paracord / Magnetic Toy

This is a fun, hands-on toy that combines simple mechanics, magnetic interaction, and 3D printing into one eye-catching creation. Designed with a central 3D-printed sphere, paracord legs extend outward along the X, Y, and Z directions, each ending in a uniquely shaped foot that contains a strong magnet. This allows the toy to "stick" to magnetic surfaces in playful, poseable ways. Whether you're into DIY toys or enjoy creative builds, this project is a great way to blend design, movement, and interactivity. Follow along to make your own!

Tools:

1. 3D Printer
2. Scissors
3. Tape Measure
4. Lighter

Materials:

1. Filament
2. Paracord - 4mm (~ 4.5 feet)
3. Magnets - 7mm x 2mm (x6)
4. Superglue

CAD Images

Print files. You will need:

1. Ball (x1)
2. Cord_End (x6)
3. Cord_End_Bottom (x6)

Cut 3 pieces of paracord to 18" long. Use a lighter to clean up the ends. While still in the melted state, pull a wet rag across the ends to remove the melted ball. This is important since the cord needs to fit through small holes.

Feed the cord the Cord End. Tie a knot. This prevents the cord from pulling back through the hole.

Trim excess material.

Insert the magnet in the Cord_End_Bottom. This should be an interference fit, which will require force. If loose, use glue to ensure it stays in place.

Attach Cord_End_Bottom to Cord_End. Depending on your printer/settings, this could be an interference fit. Mine was slightly loose, so I used superglue for the attachment.

Feed the other end of the paracord through one of the holes on the ball.

Repeat the process for the other cord assemblies. For the other ends, check the magnet's polarity before pressing it into the printed part. This is important if you want the magnets to stick together (vs. repel) later.

Keep in mind that feeding the cord becomes more difficult as you progress. For the last pass, I had to push on the other two cords to move them away from the center of the ball. I also used a needle to help guide the cord to the back hole. I eventually got it. You have now finished the toy!

Ok, so what can you go with this? Unexpectedly, I found the cords support the ball so it can be positioned like a spider-like alien.

Next, I went around the house looking for ferromagnetic materials to attach the toy. I'm not very imaginative so I could only find three quick places: switch plate, a curtain rod, and the side of my truck.

It was a fun little project. Please post if you build your own or any type of variant. Thanks for viewing.
