Omni-Directional Bookshelf Speaker

Introduction
This is a 3D-printed speaker enclosure inspired by the iconic design of the Canon S-50. While Canon has long since discontinued their legendary audio line (including the S-30, S-50, S-70, and the rear V-100S), the demand for high-quality omni-directional speakers remains. I decided to create a modern, DIY-friendly tribute that captures the retro-futuristic aesthetic but is optimized for readily available components.

Acoustics & Design
The internal volume and bass-reflex (ported) tuning have been meticulously calculated specifically for the FR090WA02 driver (8 Ohm), which is popular and easily sourced in my region. The port length and cabinet size are tailored to deliver a balanced low-end response from this full-range driver.

Key Features:
Omni-Directional Sound: True 180-degree sound dispersion, just like the classic Canon models.
Versatile Mounting: The base is designed with mounting holes for placement on a horizontal surface (desk/shelf) or easy wall mounting (keyhole mount).
High-Quality Terminals: Accommodates Audiocore LCO310 binding posts / speaker terminals (see specification sheet in the files).
Efficient Printing: Designed to minimize support material.
Hardware Required (per speaker):
1x FR090WA02 Full-Range Driver (8Ω)
1x Audiocore LCO310 Terminal Cup
2x screws for wall mounting (if applicable)
Speaker wire & dampening material (optional, recommended)

Printing Settings:
Material: PLA, PETG, or ASA recommended (PETG is preferred for rigidity).
Layer Height: 0.2mm
Infill: 20% - 30% (Grid or Gyroid)
Supports: Minimal supports may be required for the terminal housing overhang. (Check the preview).
Orientation: Print with the base flat on the bed.

Notes:
I have attached the specification sheets for both the driver and the terminal in the "Files" section for your reference.
This is a passive speaker; you will need an external amplifier.
