Stacking stand for bambulab spool - stackable

This model allows you to stack your filaments on top of another.The base has dots which snap into spool's holes where you would secure your filament.You need to also print a block which goes into a holes of square to secure them on top of each other.I recommend to not to stack more than 2 at once, even though more a possible.Boost MeHi!
