Simple Filament spool Holder Dry Box

This is the simplest system for fixing the filament spool for Box (cereals).I have seen too many complicated models, while with this you can print in just 15 minutes, only 3 essential pieces to slide the spool. For assembly you need simple self-tapping wood screws. Take the measurements, make the holes first with a screwdriver drill to avoid breaking the plastic box.The cylinder must be inserted with the flat part facing down.
