Hotel Chocolat Velvitiser Sachet Holder

My first model I've designed came around from my Mum getting a Hotel Chocolat Velvitiser for Christmas and wanted a better solution to store her sachets, whether they are cold or hot sachets.

The holder holds 10 sachets per tray with a slot at the front for the plate identifying whether they are hot or cold formula sachet, with the trays having interlocking notches to keep them next to each other. I've also added little cut outs in the bottom for the placement of little rubber feet to put to stop the trays from sliding around kitchen top counter.

Thank you for your time reading this and hopefully like the model and any feedback would be appreciated so I can aim to improve and get better.
