3D Printed BOOMBOX
Introduction: 3D Printed BOOMBOX
Hey everyone how you doing!
So this is my 3D Printed BOOMBOX Bluetooth Speaker which is a completely 3D Printed Speaker setup that houses Four Speakers with a 100W Bluetooth Audio Amplifier Module based on TTPA3116D2 100W Audio AMP IC.
Originally this was supposed to look Shiny and metallic because of a Metal finish Paint but I have done any surface finishes on it yet.
So the first thing that comes to mind after seeing this speaker is, it's pretty huge, and making this huge speaker did cause me a lot of problems.
here's the first problem, currently I only had an ender 3 printer which works perfectly but due to its small built plate, I had to print parts in pieces which really took a lot of time.
approx 50 Hours.
then there was a warping issue, and other small stuff like bed leveling problem, print failed mid-time, etc. each of these snags was all a chance to learn something and we can do better next time.
Aside from all the problems, in the end, I completed this project which took more than a week, and the end result looks and works perfectly.
As for the painting process, I'll prepare a separate video about the filling, priming, and painting of these 3D Printed parts soon!
In this Instructables, I'm gonna show you guys the whole built process of this Speaker setup.
So let's get started!
Supplies
These are the stuff that i used in this built-
* Speakers 1Ohms x2
* Speakers 8Ohms x2
* TTPA3116D2 100W Audio AMP Moudule
* 3D Printer Filament
* DC Barrel Jack
* 12V Li-ion Battery Pack
* Diode SR206
* 3mm LED
* 10K Resistor
* Rocker Switch
* Nuts and bolts M5 x 20+
* Nuts and bolts M3 x 20+
* Screws 2.2mm x 10+
Step 1: AUDIO PART
So the speakers that I'm using are from my old home theater setup made by Samsung, I salvaged speakers from it and prepared a Body or an enclosure for them.
Also, this speaker setup is made in such a way that we can add two more speakers to make it a 3x3 speaker with much more power output.
Here's how this is possible-
* I've placed two-speaker on the left side and two on the right side
* On each side, two speakers are housed in their bodies.
* we prepare a new speaker body and add it in between these two on both sides.
the result will be a much taller BT Speaker which will be louder than the current setup but that is just a point for a later improvement.
Step 2: Let's Start First With the Materials That I've Used
Making a BT speaker requires very fewer parts, you need a driver which in my case was a 100W*2 Bluetooth Audio Amplifier Module, this module uses TPA3116D2 which is a 100W Filter-Free Class-D Stereo Amplifier, I got this from PCBWAY's gift shop.
PCBWAY gift shop is an online marketplace where you can get a variety of electronics modules and boards for their genuine price or you could use the PCBWAY currency which is called beans.
You get these beans after ordering something from PCBWAY as reward points or you can also get them by posting any project in the PCBWAY community. Check PCBWAY out for getting great PCB service from here- https://www.pcbway.com/
Then I used more than a roll of filament in this project.
The filament material was PLA and color doesn't matter because I'm planning to give this speaker metallic silver paint soon!
Step 3: Designing Part and 3D Printed Parts
I modeled this speaker in fusion360, the modeling part took time but the end result was a nice-looking BT Speaker that is made in parts.
In total there are five separate enclosure sections that will be attached to each other with help of nuts and bolts.
Now, here's an issue, each body was taking a too long time to print even with a 0.5mm nozzle, so I divided each model into two parts, top, and bottom.
I printed all the parts in two sections, so I had to make them a single part again by gluing them together with superglue, you can use a special 3D Print material glue here but normal super glue will work fine as well.
I did this with a total of 5 sections and the end result was a complete single PC enclosure for each speaker.
Also, about the print settings, I used a 20% infill with supports, 0.2mm layer height, and a 0. 485
