All parts of this design, apart form the feet, can be cut from 1 200x300mm (A4) sheet of MDF or other materiel.

My 5w D1 Pro cut and engraved all parts using the settings listed above in around 35 minutes. 

once all parts have been cut the 4 sides should simply slot together and be strong enough without any glue.

I would recommend adding a little glue to the bottom to add extra strength. Any wood or super glue should work for most materiels.

First the 12mm circular spacers should be glued to the back of the feet.

Once the glue has dried the feet can be stuck to the front of the storage tub.

Be carful not to overlap the feet below the bottom of the tub or the finished product will not stand up properly.
