CD Player Cube
CD-Inspired Body Inlay Module
The body inlay features engraved details such as “MUSIC” and “FROM ZERO TO ONE”, with the outline faithfully recreating the opening shape of a classic CD player lid.
Iconic labels like “JAZZ” and other markings echo the function buttons of vintage music players.
The layout includes Random Play and Single Repeat button-inspired elements, with a small heart-shaped accent button adding a playful design touch.
This isn’t just visual nostalgia — it also features real metal dome button feedback.
A dedicated lower “music playback” button delivers a crisp, solid click, recreating the satisfying press feel of old-school portable CD player buttons. A true retro tactile stress-relief experience.
Precision Engraved Details
All characters and surface textures are created using high-precision etching, resulting in:
- Sharp, clean edges
- No burrs or roughness
- A refined, premium finish
Enhanced Play with Square Core Side-Push System
Paired with the Square Core side-push mechanism, the PEEK Dense Track (Version A) delivers a silky segmented motion.
Combined with the mechanical button feedback, the tactile experience is layered, immersive, and highly satisfying.
Modular DNA – Unlimited DIY Possibilities
Continuing the modular design philosophy, the 01 EDC Square Core retains its full DIY capability.
Users can freely customize the feel by:
- Replacing track plates
- Adjusting springs
- Changing bead configurations
Switch between different segmented feedback styles to create your own ideal tactile setup.
Universal Compatibility Across the Series
Whether purchasing a new CD-style base Square Core or just the CD body inlay module, all versions are fully compatible with existing Square Core units.
Mix and match freely to build your personalized EDC setup.
Magnetic Attachment – Tool-Free Upgrade
The inlay attaches via strong magnetic mounting, requiring no tools.
You can easily give your Square Core a “new CD-player skin” in seconds — a low-cost DIY upgrade that brings fresh life to your favorite everyday carry piece.
