Modular 3D Printed Desktop Speakers

This project is a pair of compact, full-range desktop speakers designed from scratch and optimized for 3D printing.
Each enclosure features a built-in slot-style bass reflex port, tuned around 85–90 Hz, delivering surprisingly full low-end for its size while maintaining clarity and balance.

The speakers were designed to sit under a monitor shelf for a clean, minimal desktop look — but the shelf holders can be removed or modified on request if you’d like to use the speakers as standalone units.

I’ve also designed the internal structure with acoustic damping in mind, and the walls are thick enough (2 mm) to ensure a rigid, low-resonance enclosure. The result is a punchy yet controlled sound that’s especially good for near-field listening.

I am no audio mechanic by any means but i did my best te create something durable and easy to print with minimal supports. Just the reces on the front needs supports. I have specified the supports in the 3mf file

The speaker is based on the Dayton Audio CE70PR-4 but other 70mm drivers should fit.

Magnets for front gril 8x2 (8 per speaker)

Heat inserts to accomodate 3x10 mm screws for the backplate

There is a gasket for the backplate that you can print in TPU. You can do without just raise the z Heigt of the backplate by 1mm before printing. There is room for a 85mm wide shelf, length is up to you but might need a support if to long.
