A desktop‑grade filament holder specially designed for small 200–250 g spools, integrally 3D‑printed and tailored to compact, entry‑level 3D printing setups.

  Structural and Functional Details

- Modular Quick‑Assembly Design: Composed of dual support bases and a central shaft tube, with a slot‑based mounting system that allows rapid assembly and disassembly without additional tools, making filament changes even more convenient.
​
- Lightweight yet Stable Construction: A trapezoidal hollow base balances structural rigidity with weight reduction; pre‑drilled mounting holes enable secure screw fixation as needed, preventing displacement during filament feeding.
​
- Low‑Friction Shaft Compatibility: The shaft diameter matches the inner diameter of small‑size filament spools, ensuring smooth filament rotation, reducing feed resistance, minimizing jamming risks, and supporting most mainstream desktop 3D printers.

    Key Advantages

- Optimized specifically for 200–250 g small spools, this holder features a compact footprint that saves valuable desk space, making it ideal for mini printers and compact workstations.
​
- Entirely 3D‑printed, requiring no additional hardware components—low cost and highly adaptable.
​
- Open‑design facilitates easy filament replacement and provides clear visibility of remaining filament, perfectly suited for small‑batch printing needs.
