I have 2 Ikea Samla filament storage containers with 4 spools in each container. Created this block to have 4 combinations of filament to funnel into 1 port for both containers. Using this block with my Snapmaker J1S Idex printer to make storing and swapping filaments a bit easier and to keep lines organized. I'll have to open the container lid to feed or retract filament from the extruder back past the splitting block.

Print Settings: Pretty basic settings

Layer Height - .20mm

WallCount - 3

Infill - 20%

Print Orientation - Printed on the 2 port side face
