3D Printer STL files for audio source switch and volume control boxes. JocysCom-Switch.zip file size ~17MB.
Below you will find parts and tools, which will help you to print and assemble audio source switch and volume control boxes. If you noticed mistakes, have questions or suggestions, know better component (available in EU and US), please write or send link to info@jocys.com • Project on Thingiverse.com or Printables.com
Parts were printed from PETG with Prusa3D i3 MK3 Printer. If your printer is not precise enough, printed parts may not fit into each other and may not look good.
If you made your own updates or changes, related to this project, please send me a link. I will add this link to your work on this page.
Why I decided to make my own switch? I tested few audio switches. Ground wires of both audio sources were connected together in all of them. Why? I understand, that manufacturers can save few € by using cheaper switches with fewer poles, but consequences of that are unacceptable. Unnecessary ground merging creates audio noise and anomalies. You need to buy and use ground loop isolators to eliminate this noise, but ground loop isolators degrade quality of the audio slightly. I wanted audio to go through ground loop noise isolators ONLY, when both audio sources are merged (when you want to hear audio from both computers at the same time). To avoid audio merging, while switching sources, I used non-shorting switches. Also, I wanted to switch headphones and stereo microphone with ability to switch off (disconnect) microphone completely. With stereo microphone you can have better environment noise elimination options in software. I didn’t want to use powered audio mixers or interfaces, which needs power and processes (distorts) signal in any way.
Features:
1. Microphone switch: PC1 • OFF • PC2.
2. PC1 audio volume control.
3. PC2 audio volume control.
4. Audio source switch: PC1 • PC2.
5. Audio source merge: PC# (OFF) • PC1 + PC2 (ON) - audio signal grounds of PC1 and PC2 are merged and audio goes through ground loop noise isolators ONLY, when audio signals are merged. This allows to avoid audio quality degradation, when unnecessary and you don't need to listen both computers at the same time.

Kester 44 Rosin Flux is an activated rosin formula for use in flux-cored solder wire. 44 has virtually dominated the field of activated rosin core solders for well over four decades. An outstanding performance feature of this flux is the “instant-action” wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production line soldering. 44 is classified as ROM1 per J-STD-004.
Sn60Pb40 - 0.8mm - 3.3% Flux - melting range 183-190°C

PETG Filament
PETG Filament

I would not recommend to print parts from ABS (shrinkage is too big) or PLA (low heat resistance). Light colour prints are quite demanding and require higher quality filament and printer precision, because light filaments don't mask print imperfections as well, as black filaments do.

Printing Settings
Printing Settings for PETG Filament on TEXTURED PEI Powder-coated Spring Steel Sheet
For BIG parts to stick on TEXTURED PEI Powder-coated Spring Steel Sheet, I increased bed temperature for AmazonBasic • BasicFil PETG filaments from recommended 60-80°C to 85°C (First layer) and 90°C (Other layers). I printed BIG parts in my own Temperature Controlled Enclosure. Temperature inside enclosure was 35°C. E3D V6 HotEnd is rated to 40°C ambient operating temperature. As you approach that temperature, cooling efficiency is reduced, allowing more heat up past the heatbreak. This can cause low temperature filament to soften in the mechanism to cause feed problems.
