Unique DIY Spiral Speakers

Hey everyone! 

I'm super happy about the reaction to my recent YouTube video where I designed and built this pair of speakers. A number of people asked for the files to print their own, which is awesome – so here they are!

Need help on the assembly, or parts list? Check out the video below! 

Required Non-Printed Parts:

• Dayton Audio PS95-8 3.5" Full-Range Drivers (x2)
• Mini Stereo Amplifier (e.g., Nobsound Mini Amp, Fosi Audio BT20A, Douk Audio G3, or similar)
• Speaker Binding Posts (x4)
• Speaker Wire (16ga, length as needed)
• M3 Heat-Set Inserts
• M3 Screws
• PLA Filament (Or PETG/other stiff material)
• Soldering Iron & Solder
• Wire Strippers/Cutters
• Optional but strongly recommended: Sound dampening material (Polyfill, foam)
• Optional: Gasket tape or sealant for airtight enclosure

Printing Recommendations:

• Material: PLA is generally recommended for stiffness, but PETG or ABS could also work.
• Layer Height: 0.2mm recommended for a balance of speed and quality.
• Infill: 50-75% should be sufficient (Gyroid pattern recommended). Consider higher infill or more walls for increased rigidity if desired.
• Supports: Supports will be needed due to the curved overhangs. Tree/Organic supports work well. (3MF file includes pre-configured supports).
• Orientation: Print parts in the orientation provided in the files for best results. You can split the tail in half if you are having trouble printing it.

Assembly:

Please refer to the YouTube video linked above for the detailed assembly process!

Notes:

• As heard in the sound test (see video!), these speakers offer great clarity, especially in the mid-range and highs, thanks to the full-range drivers.
• Like many smaller bookshelf speakers, they will benefit significantly from being paired with a subwoofer for full low-end bass response.
• This is a DIY project involving electronics and 3D printing. Results may vary based on print quality, assembly precision, and components used.

Enjoy the build! I'd love to see your makes – please share photos if you print them! Don't forget to check out my YouTube channel for more projects. If you have questions, ask in the comments below or on the video! Happy Printing!
