Modular Tray System for 55L Ezystorage Tubs

This modular two-part tray system was originally designed for long-term filament storage inside 55L Ezystorage Bunker Tough tubs (58 x 38 x 40.8 cm). These containers are stackable, water- and dust-proof, making them ideal for protecting sensitive materials from moisture and environmental exposure.Each tray is split into left and right halves, with matching lids that are fully interchangeable — rotate them 180 degrees and they still align perfectly with the tray recesses. This symmetry ensures that the left lid fits the right tray and vice versa, simplifying use and assembly.The trays are designed to hold silica beads, mothballs, or other protective agents — anything you want to use to preserve or protect the contents of the tub without direct contact. I personally use 300 grams of silica beads per tray, which is more than sufficient for the internal volume of the 55L container. This creates a separate airflow zone inside the tub, allowing desiccants or deterrents to work effectively w
