About this 3D model

One of the big problems with vacuum packing a spool of filament is that of the deformation of the spool. I created spacers that allow you to avoid this unpleasant vacuum effect. They can be used for 4 or more. They have a size that works well with the original BambuLab coils or clones of the same or, even with coils that measure an internal height of approximately 59mm. They can be made of PLA or other material; I preferred to build them with a wall of 3 and an infill of 25% to make them more robust; and I rounded the edges in contact with the plastic of the casing to prevent it from being damaged during the suction process.
