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.
