Introduction: Bluetooth Speaker With Ironman Design

The concept of this work is an iron man style bluetooth speaker that seems to work as an arc reactor.

Step 1: Materials

1. 5V LEDs (20pcs)

2. Lithium battery & Battery holder

- I used 3500mAh of 18650 standard.

3. PAM8406 Bluetooth speaker module

4. 3Inch 4ohm 10W speaker (2pcs)

5. Copper wire

- 0.6mm thickness solid wire , Length : min 11meter.

6. Charging & Booster module

- 3.7V 9V 5V 2A Adjustable Step Up 18650 Lithium Battery Charging Discharge Integrated Module

7. Micro push switch

8. 1.8V RED Color LED

- If you don't need the charge indicator, you don't need to buy it.

9. Variable resistor

- 500ohm or 1K

10. AWG#22 Cable 3meter

Step 2: 3D Printing & Wire Diagram

Layer Height : 0.2mm

In Fill : 20%

Top/Bottom Layers : 3

Wall Line Count : 3

Filament Material : PLA

Supports : Middle Body, Coil Pad (Overhang Angle : 50)

Light ring parts must be printed in white or transparent filaments.

Step 3: Remove Supports / Post Processing

1. Remove support from middle body and coil pad.

2. Roughly rub the surface by #220 of sandpaper.Because it will be filled the scratches in putty later,So you can roughly.

3. Mix red-putty with acetone or paint thinner for Dilution

4. Apply diluted putty to the product surface using a brush. Apply it twice so that there are no print marks left.

5. Rub with #400 of sandpaper first, after then rub with #800~#1000 of sandpaper to smooth more.

6. Painting.
