The standard filament holder for 3D printer JGAurora A5/A5S is designed for coils with thickness of up to 74 mm. I use a coil of a large size, so I modelled a special nozzle, which increase the size of the holder up to 82 mm.
These models are printed very easily and quickly. Do not require a large amount of plastic, do not require supports and raft.
The diameter of the holder tube is approximately 32.5 mm.
The inner diameter of the thing 32 mm to ensure that they are well kept.
The outer diameter of the thing is 44 mm.
