This design, crafted from 5mm-thick MDF (27cm x 29cm), houses your 3D printer's filament feed and can be laser-cut using the provided file.

As for the axle, use whatever hardware you have on hand to ensure a fixed length slightly longer than your coil width for optimal support; incorporating a bearing system would further enhance its solidity.
