Introduction: DIY Speaker Reusing 3D Filament Spool

About: Maker | Innovator | Electrical Engineer

Everyone wants the speaker in Room or on the Desk. When you own a 3D printer you deal with an empty filament spool, however not every time throw in the garbage, use for storage or wires reel. Let make the Speaker using an Empty 3D Filament spool.

In this project, Reusing the 3D Filament Spool for making Speaker. Here I use a high-quality speaker with a Bluetooth circuit and some RGB LED strips. This project is very easy to make, hope you enjoy it to make.

The result came out was amazing !!!

Supplies

  1. Empty 3D Filament spool (22cm outer diameter and 5cm inner diameter).
  2. RGB LED Strip (1.5 meter).
  3. Speaker (4 watt). (5cm in diameter)
  4. Bluetooth Circuit 12v (only 1).
  5. 7805 IC (only 1).
  6. DC Jack (only 1). (13mm diameter)
  7. Switch (only 1). (13mm diameter)
  8. Arduino pro mini. (only 1).
  9. 12v adapter (only 1).
  10. TTL to USB - FT232RL (only 1).
  11. Wires (multi color).
  12. 3D printed parts.

Note: Buy Speaker size according to inner diameter of filament spool.

Step 1: Design in Fusion360

Edit Fusion360 (f3d) file according to your requirement. download it below.

Step 2: 3D Print Parts

Print all parts in Transparent filament.

Note: Print Hole Plate - 2 quantity.

Step 3: Paint the Spool

Tips: Coat main color on spool then sprinkle some color on it using brush.

Step 4: Solder Wire

Solder wire of LED Strip, Jack, Switch and Speaker.

Step 5: Drill 13mm Diameter Two Holes at Back of Spool

Drill two holes at back of spool of 13mm diameter.

Check note in image.

Note: Refer above image hole position.

Step 6: Drill 3mm Hole As Shown in Image

Check note in image.

Step 7: Coil Up the LED Strip Inside of Spool and Pass Wire Through 3mm Hole

Check note in image.

Step 8: Stick the Led Strip Inside of Front Side of Spool

Note: Pass Wire Through 3mm Hole

Step 9: Insert Speaker Into Spool

Glue the speaker with spool and speaker should faced front.

Step 10: Insert the DC Jack, Switch and Hole Plate at Back of Spool

Glue the hole plate with spool.

Step 11: Insert Hole Plate at Front of Spool

Glue the hole plate with spool.

Step 12: Upload the Code to Arduino

Connect TTL FT232RL to Arduino pro mini. Then upload the code.

Step 13: Wire Harness Diagram

Refer above image for wire connection.

Step 14: Complete All Wire Harness and Wire Management

Stick all Circuit on the inner side of spool.

Step 15: Test All Things

Step 16: Insert and Glue Both the Circular Rings Around Spool

Step 17: Place on Stand

Step 18: Plug the Power

Step 19: Finished!!!
