Structural Design

1. The base and supporting columns feature multiple integrally molded reinforcing ribs, forming a triangular, stable support structure that significantly enhances overall load-bearing rigidity, ensuring that long‑term storage of filament spools prevents bending, deformation, and edge warping.

2. A horizontally贯通 (through‑going) support shaft is compatible with standard 200‑g filament spools, with limit stops at the shaft ends to ensure smooth rotation without misalignment.

3. An all‑in‑one, seamless printing structure distributes stress evenly, providing stable load capacity and accommodating conventional small‑size filament spools.

Core Applications

Specifically designed for 200‑g compact 3D‑printing filament spools, this accessory sits on a desktop beside the printer, allowing the spool to rotate freely while ensuring smooth filament feed and preventing jams.
It also serves as a convenient desktop organizer for storing leftover short lengths or sample filaments, minimizing the risk of spools rolling off or filaments tangling—ideal for everyday use with small‑form‑factor FDM printers.

Process Compatibility

PLA and PETG are recommended; the built‑in internal reinforcing ribs eliminate the need for additional tree‑like supports, resulting in a robust final print that resists deformation and cracking over prolonged use.
