Air rail easy spin filament holder
thingiverse
The "air rail easy spin filament holder" relies on a 120mm fan to generate a powerful air pocket beneath the slider part, allowing the spool of filament to slide smoothly across its surface and reveal any underlying stress on your 3D printer's motors and gears. It's essential that all parts be printed with 100% infill due to the substantial weight of the spool, which can cause stress on the frame. For optimal results from the rail, using a higher-powered fan will minimize friction between the rail platform and slider. Assemble the parts by employing a hot glue gun for best results, as it creates a reliable seal with minimal air leaks. However, you can also use duct tape if needed, though the more effective the seal, the better this assembly will work.
