3D Printing - repairing a Jlab headphone

For many years I did buy a headphone from a company called Jlab.
They are cheap (< 30$) and very good sound quality and comfort.

I think I did buy so far 4 or 5 headsets and the reason is because after a while they broke down.

Finally I was able to repair one !


The headphone from Jlab I'm talking about is this one (can be easily found on WalMart and Amazon and many other places) :

The sound quality and comfort of this headset is quite high, however there is a small piece of plastic that after a while broke down, rendering totally unusable the headphone.
The piece that always broke down is a small piece that connect physically the speaker with the headphone band.
Here some pictures of the broken piece and it's location.

Position of the broken piece

The original piece broken down

This time having the 3D printer I decided to try to design a replacement .. and I did it !
Using Tinkercad I designed a replacement for the broken piece and then printed out.

G-code file preparation

Once downloaded the STL files I did open it with the slicer Cura Master version on LXDE Ubuntu 18.04.

The project is a single STL file

Here the setting I used for the  STL file in the project:

• Material : Hatchbox white PLA 
• Printer : Ender 3 Pro   (stock but with yellow springs and glass bead)
• Layer Height : .12 mm
• Wall thickness : 1.2 mm
• Wall Line count : 3
• Top/Bottom thickness : 0.84 mm
• Top/Bottom layer : 7
• Shell :
• Wall thickness : 1 mm
• Wall Line count : 2
• Infill :
• 90
• Cubic
• Material :
• Printing temperature : 200 C
• Build plate temperature : 60 C
• Enable retraction
• Speed :
• Initial print speed : 45 mm/s
• Print speed : 60 mm/s
• Build Plate adhesion :
• Brim 

The file was then uploaded to OctoPrint for the print.
The piece takes about 11 minutes to be printed.

The final result

Here's the fixed headphone
