Gridfinity Spool Holder for P1 & X1

This Spool Holder bin is inspired by FOSBOS - Spool Holder Bin but made specifically for Gridfinity. Unlike the original, this bin allows you to stack other Gridfinity bins on top and takes much less vertical space, allowing you to store more bins in your Gridfinity setup.This is perfect if you use AMS and want to keep your Bambu P1/X1's External Spool holder stored in your Gridfinity for future usage.
