Under cabinets drawer

I had some things to stock and no space over my work table, so I decide to stock a lot of materials appended to the cabinets. I thought for a simple way with a sled system that could be printed easily and hold good weights and this came out.
the thickness of the drawers is 3 mm and they are printed in PLA with 0.6mm nozzle, 0.4mm layer height, 2 perimeters and 25% infill, I like robust things and in fact they have the ability to support a good weight. The slides are inclined and with end stop so as to keep the drawers safe in position with their weight.
After printing nothing is needed. I only made squares of trasparent films to insert in the label pocket because the labels on PLA do not want stay attached for more than 1-2 days.
