Amplifier Speaker Selector

Hi Everyone, I designed this enclosure to safely connect two amplifiers to a single set of speakers. If you find yourself in the same situation, this is a simple, reliable way to build your own amp/speaker switch box. It can also be used for blind A/B listening when running one amplifier with two different speaker sets. All components are readily available online, and the build requires only basic tools. Parts Required 1× Banana Plug Wall Plate for 4 Speakers 1× Banana Plug Wall Plate for 2 Speakers (or individual speaker binding posts) 4× M3 Countersunk Flat Head Phillips Machine Screws (10 mm) 1× 4PDT Toggle Switch, 2-Position, ON/ON, 12-pin mounting hole diameter: 6 mm (can be enlarged slightly with a drill if needed) Printing Import the model into Bambu Studio “Paint” the enclosure in your preferred colors Print using standard settings suitable for your chosen filament. Assembly Cut the wall plate to fit the enclosure. This is easily done with a utility knife or sharp wire cutters.
