I needed a switching module to connect two 3.5mm jack connectors to a single line in on my speaker. I bought the following switch from Audiophonics. I designed the little case so the module is less exposed and blends in a little more with the surrounding. I just used double sided tape to stick it to the side of my sideboard.
I used the cut function in PrusaSlicer to split the model and added some connectors. You can also find the uncut version in the model files. The module also has an XH2.54mm connector to add a second output connector so if required, you could easily add an opening with the “Add negative volume” function in PrusaSlicer.
Happy printing.
