How to Make Your Own DIY Fidget Spinner?

Fidget spinners exploded in popularity in 2017 as the must-have toy and distraction for kids and adults alike. While you can easily buy pre-made fidget spinners in stores or online, making your own at home can be a fun craft project. With some basic supplies and tools, you can create a customized fidget spinner to your specifications. Here is a step-by-step guide to making your own simple fidget spinner at home.

Supplies Needed

  • 3D printer or access to one
  • PLA plastic filament
  • Bearings – you’ll need 608 ball bearings with measurements of 8mm outer diameter, 2mm inner diameter, and 2.5mm thickness. Be sure to get high quality bearings for good spin.
  • Super glue or epoxy
  • Sandpaper
  • Acrylic paints or spray paint (optional)

Step 1 – Print the Spinner Body
If you have access to a 3D printer, you can find and download fidget spinner templates and designs online for free to print the main spinner body. Look for a simple design with three arms that has holes or recesses to fit the bearings. Print the design using durable PLA plastic filament on a 3D printer. For best results, print with 100% infill so the spinner arms are solid and sturdy.

Step 2 – Fit the Bearings
Once printed, test fit each of the three bearings into the holes or bearing seats on each arm of the spinner. They should fit snugly. If needed, use a bit of sandpaper to lightly smooth the bearing holes so the bearings can press fit into place. Don’t sand too much or the bearings will be loose. Firmly push each bearing into place in an arm.

Step 3 – Add Glue
Add a small drop of super glue or epoxy around the edge of each bearing where it meets the inside of the arm. This will firmly secure the bearings in place. Make sure not to get glue into the bearing! Allow the glue to fully dry and set before moving on.

Step 4 – Spin It!
Check that your bearings are secure by giving the spinner a test spin. Twist the center area to get it spinning fast. If the spinner wobbles, the bearings may need more glue or be uneven. Keep adjusting until you get a smooth, fast spin.

Step 5 – Decorate (Optional)
If desired, you can paint or decorate your DIY fidget spinner to personalize it and make it look more fun. Carefully apply acrylic craft paints in your desired colors and designs to the outer arms and center using a small brush. You can also use spray paint to cover the whole spinner. Apply thin coats to avoid clogging details, allowing each coat to fully dry between applications. Add decorations like stickers or glitter once the paint is dry. Apply a clear sealant spray to protect the paint and give your spinner a nice glossy finish.

The great thing about 3D printing your own fidget spinner is you can customize and personalize it however you like. Tinker with the shape, size, colors, and more. Change the design to be two-armed, four-armed, or any number of arms. Experiment with patterns and shapes on the arms. Print multiple versions and spinners to compare spinning times. With your own 3D printer and a bit of creativity, you can create an amazing customized fidget spinner to show off and keep your hands busy.

No 3D Printer? Make a Cardboard Spinner
Don’t have access to a 3D printer? You can also easily make a simple fidget spinner out of cardboard and paper fasteners. Here’s how:

Supplies Needed:

  • Cardboard – thin cereal box cardboard works great
  • Paper fasteners or brads
  • Scissors
  • Ruler
  • Pencil
  • Decorating supplies (markers, stickers, etc.)

Step 1 – Cut Cardboard
Use a ruler and pencil to measure and mark shapes on the cardboard. You’ll need three arms in the shape of isosceles triangles. Cut out the three arm pieces. Make them at least 3 inches long from base to tip.

Step 2 – Attach Arms
Use a paper fastener or brad through the center point where the arms meet to attach the three arms loosely together. Allow them to spin freely.

Step 3 – Decorate
Personalize your cardboard spinner by decorating the arms with markers, stickers, glitter, etc. Allow to fully dry.

Step 4 – Spin Away
Flick the center to start your cardboard spinner spinning. Experiment with different arm shapes and sizes to optimize the spin time.

The simplicity of cardboard makes it easy to create new spinner prototypes quickly. Make a whole collection of different fidget spinners out of materials around the house for free.

Whether you 3D print a pro-level spinner or craft one from cardboard, making your own DIY fidget spinner is an enjoyable and rewarding project. Follow these simple steps to create endless spinning fun and a unique fidget toy you made yourself.
