Filament Buffer for long Filament Paths

I have a long reverse bowden tube on my printer and thus needed a large buffer array for automated filament changes with an mmu. I designed this filament buffer to accommodate up to 1 meter retractions but by cutting down the front section you can customize the length to fit your needs. The face is removable while assembled by flexing the mandibles. If you are looking for less exposure to air you can print the solid wall parts, otherwise you can save material by printing one set of hex wall parts to cap the end. The only hardware needed is PC4-M6 bowden couplers (2 per buffer unit) and 8mm all-thread/nuts for mounting hardware.

Feel free to remix or create additional face designs!

I printed mine with a .4 nozzle; 2 perimeters/top/bottom Shells; 18% infill; .3mm layer height
