This is a CD storage tray I’ve optimized specifically for 3D printing, boasting an exceptionally simple construction that ensures fast, highly efficient printing.

The entire model features an integrated design, free from complex assembly parts or overhanging structures that require supports. With a single-layer wall thickness and strategically placed hollow sections, it maintains robust load-bearing capacity while significantly reducing material usage and print time. Typically, it can be printed in just one to two hours, allowing you to quickly produce a practical, functional result.

In terms of design, the tray ingeniously incorporates snap‑fit slots that not only securely hold CDs upright but also make them easy to insert and remove, effectively protecting the disc surfaces. Its compact layout maximizes space efficiency while keeping everything neatly organized.

This storage tray is a prime example of “efficiency-driven design”: it makes 3D printing effortless and swift, transforming digital models into beautiful, practical everyday items with minimal time investment and the simplest possible workflow—making it the ideal choice for beginners in the maker community or for those looking to quickly complete their printing projects.
