DIY Bluetooth Speaker 2.1 - Small but POWERFUL! | by Sebastian

Hello, my dears! Did you miss me? ❤️‍🔥 After almost ten months, I'm bringing you a new DIY video, featuring a second speaker made using 3D printing technology and laser engraving! Work on the project began in December 2025 and finished at the end of January 2026. The speaker, measuring 25cm x 20.6cm x 16cm (including the handle and feet), produces a beautiful, unimaginable sound for its size, thanks to the components used. Ultimately, the speaker stole my heart because it has everything... Intriguing design, excellent sound quality, and portability. I'd like to show you the project in person, because it's just not the same here. I'll also mention that the worst part was recording the material for you at -10°C, where I wanted to give up faster than the speaker, which didn't even resist these weather conditions. For me, this is a very successful project, and its new owner has been enjoying it since the first day of February. I know I'll be able to take it to summer recording sessions, so it'll probably be on our channel again. What do you think, is a good project? Let me know in the comments. See you next time!
