3D-Printable Cassette Shelves

Compatible with Kura Curiosa

I’ve always had a soft spot for analog sound.

Living in Tokyo means limited room for vinyl, so I gravitated toward cassettes instead—perfect, in a way, because I love their plastic, mechanical presence. They’re a “cheap” medium played by surprisingly sophisticated (and nowadays expensive) machines.

My Sony WM-D6C sits right next to my laptop on my desk, and it plays most of my music nowadays.

What attracts me to cassettes (and vinyl) is the sense of intentionality that streaming lost—the album as a fully conceived artistic object: the cover, the track sequence, the notes, the physical ritual of finding new titles.

As a teenager I collected jazz CDs—I had several hundreds of them. Today, for no particular reason, I collect cassettes with loose ties to electronic music.

Since I needed proper shelves to house my tapes, I decided to print ones that matched my needs. You’re welcome to print your own modular shelves too.

modular tape shelves

Concept

>_ A minimalist storage system that works both as a standalone object and as part of a larger modular wall arrangement.

>_ Stackable (horizontal and vertical), low material consumption, relatively fast to print.

>_ Material: PLA or PETG
Supports: Not required
Stacking: M3 square nuts and M3 x 8mm screws
Mounting: Placeable on desk or mountable on walls (need optional modules with central hole)

Kura Curiosa Compatible

>_ Although this project wasn’t designed as part of the Kura Curiosa universe (my DIY art collection), I aligned its proportions and spacing with the system’s existing dimensional logic. This means the cassette shelves integrate naturally alongside Kura Curiosa modules—both visually and spatially. You can arrange them within the same wall grid, combine them in mixed displays, or even treat them as functional blank panels for a large Kura Curiosa instalation.

The compatibility is intentional, but the usage is entirely up to you.
