Really Useful Box Tray

Here is my adaptation of the removable tray for some of the larger Really Useful Boxes, specifically the “Large 12 Compartment” variant. Each of the RUB trays is equivalent to 6 of these. It's worth measuring and adjusting the size of them to your needs as the A1 Mini version is slightly smaller and due to tolerances, etc. Specs directly from the website:DimensionsExternal: 375mm x 310mm x 90mmInternal (each compartment): 95mm long x 90mm wide x 87mm high suitable for RUB11, RUB18, RUB20, RUB21, RUB35, RUB50, RUB64 and RUB8411 & 18 litre Really Useful Box can hold 1 tray20 & 21 litre Really Useful Box can hold 2 trays35 litre Really Useful Box can hold 3 trays50 litre Really Useful Box can hold 4 trays64 litre Really Useful Box can hold 6 trays84 litre Really Useful Box can hold 8 trays
