Hello everyone, this is my interpretation of a filament holder specifically designed for the 4-liter cereal boxes. The parts can be easily assembled without any tools (pressfit) and provide a stable solution for the storage and passive drying of filaments.. The holder can also be used independently. It is ideal for small systems, as the low rolling resistance allows for direct and easy printing from the boxes. The parts are optimized for printing on the build plate of the A1 Minis.
