I build an entire wall wood Shelving and Counter for my soldering and small parts drawers. The top shelf holds my larger maker items such as motors and computer parts. Under the counter is my server and amplifier racks. I made the left side into my kitchen area and my bookcase under that.
To tie the shelves to the 2×10 boards I used for the 4 main legs, I used Shelf brackets (Amazon) for stability and also used 2x large screws into the 2×10 boards through the 2×4 under shelf beams to secure them. The plywood shelves were screwed into the 2×4 beams.
