3 kg spool container

3 kg spool containerSpool Box Leg and Frame Inserts for Smart Box 14LThese inserts are designed to turn a regular “Smart Box” 14L container by Aleana (Алеана) into a vertical filament storage and feeder box.Since the sides of the box are not perfectly perpendicular, these legs and frame inserts help level and stabilize the internal frame — allowing your filament spool to stand perfectly vertical inside the box.You can use this setup together with a filament spool holder — either a ready-made one (as in my case) or a printed version of your choice.Perfect for keeping filament dry and feeding smoothly from a sealed container.FeaturesCompatible with Smart Box 14L (Алеана) plastic containerCompensates for non-perpendicular box wallsKeeps filament spool vertical and stablePrintable without supportsWorks with both ready-made or 3D-printed spool holders
