Modular Prusament Spool Wall Grid

This project reimagines the new Prusament spools as a scalable wall-mounted grid, inspired by systems like an “IKEA Skadis.” Instead of throwing them away, users can transform them into a clean, functional, and customizable storage solution—without modifying the spools in any way.

The structure is built using a minimal set of 3D-printed connectors. Each junction between three spools is secured with three parts: a central triangular piece that locks the circular faces together, and two square connectors—one aligned along the flat sides and another reinforcing the remaining connections. This creates a rigid, repeatable, and easy-to-assemble system.

For correct assembly, all spools must be oriented consistently, with their flat sides facing the same direction. Users can position the spools with the inner side facing either inward or outward, as long as this alignment is maintained.

The system is designed to be mounted on a wall. Installation is simple: the spools already include holes, so only a few screws are needed to secure the structure in place. For optimal usability, it is recommended that the connectors are positioned on the back side of the spools, facing the wall. This prevents blocking nearby holes and keeps the front fully accessible for attachments.

One of the most powerful aspects of this design is the hexagonal infill pattern of the spools, which acts as a universal mounting interface. It allows users to insert custom 3D-printed components—hooks, holders, shelves, brackets—turning the structure into a highly adaptable organization system.

Due to time constraints—both from my academic, social, and спортив commitments—and the fact that I discovered this contest only three days before the deadline, I was not able to fully design and develop these additional modular accessories. However, this is only the beginning. I plan to continue improving this project by creating a full ecosystem of attachable parts that will expand its functionality.

This idea goes beyond the contest itself. It has real potential for anyone who regularly works with 3D printing and has accumulated empty spools at home. Instead of letting them collect dust, they can become part of a practical, customizable system. This is something I also plan to develop further for my own use.

This project is not just about recycling—it’s about redefining waste as a resource. A modular, expandable, and creative system that turns leftover materials into something genuinely useful.
