3D Printed Transmission Line Speaker

3D printed transmission line speakers

In this instructable,I will show you how to build a transmission line speaker.
A transmission line speaker improves the audio of the speaker by a huge amount

Gathering the Materials and Tools

For this,you will need:
- Audio Amp

- A audio jack

- A micro usb breakout

- Small speaker

Tools:
-A 3D printer(I am using the Tevo Tarantula)
-A soldering Iron
-Hot glue gun

The Case

I designed the case myself and it took ~5hrs to print.I printed it in pla plastic.

The Wiring

Now,you need to connect everything as shown in the wiring diagram

Gluing Everything

I will glue the amp and the ports on top of the speaker and glue the speaker in it's place.After that,you should test everything and see if it's still working.If so,add hotglue on the interior walls(in the center too).IF you don't glue the side panel propely,the speaker wold cause the side panel to vibrate really hard!

Done!
