Repurposed Spool Winder from Scrap Material Trays: A “Wire Storage Masterpiece” That Turns Waste into Treasure – This spool winder is a practical, eco‑friendly innovation that breathes new life into unused 3D‑printed material trays, transforming what would otherwise be idle scrap into a valuable storage solution.

Its design is perfectly tailored to fit standard material tray dimensions, and once assembled, it effortlessly organizes all kinds of cables: whether it’s charging cords, power cables, or long extension cords, they can all be neatly wound around the tray, putting an end to the frustration of tangled wires. The built‑in handle makes winding and unwinding a breeze, while the sturdy base ensures the spool winder sits securely on your desk or in a corner—combining environmentally conscious reuse with a smart, space‑saving solution for cable management at home or in the office. It’s a budget‑friendly, highly functional “eco‑friendly storage hero” that delivers both practicality and sustainability.

Installation Steps:

First, assemble the spool base and the spool itself. Be sure to snap the handle into place on the base before proceeding.

Align the cover plate with the spool, then press the other end of the handle into the corresponding hole on the cover.

Install the securing screws.

Insert the crank into the central hole, then flip the assembly over.

Attach the locking cover plate, leaving a small gap between the cover and the base—do not tighten it too tightly, as this could prevent the crank from turning smoothly.

Install the crank handle—and you’re done!
