This dual-head Buden type consumables rack is specifically designed for the Neptune series of 3D printers, but it can also be compatible with any 3D printer equipped with a spool fixing arm. I have specifically optimized this consumables rack to enable it to deliver consumables from a consumables dryer to the Neptune 4 Max printer via standard Buden tubes. The consumables rack is firmly clamped to the spool fixing arm using M3 nuts and bolts.

Set the print layer height to 0.2mm
The filling density is 10%
The wall thickness is set to 3 layers
