Printing these two symmetrical DynaShelf shelves, with 12mm sections and reliable dovetail joining, featuring assembly order symbols, took 107 hours and 4.2 kg of PLA. They are wall-mounted using 5 4mm diameter expansion screws with 7.5mm diameter heads. Note that for the highest section, 50-55mm screws are needed. I have also included plugs to conceal the screw holes.

Printed in PLA, no supports are needed.
