This cabinet is something I promised my son a long time ago. All our Lego pieces were tossed into a single box, creating a nightmare when searching for specific pieces. I wanted to build a convenient organizer to somewhat alleviate the pain of endlessly looking for items.
With the exception of the wheels, I constructed everything from scratch, from the initial design to the manufacturing phase. The entire project took approximately two weeks to complete (mainly during the evenings, since I have a day job).
#Design, cutting & assembly
I started by designing the cabinet in SketchUp (web). I wanted the top of the cabinet to have space for 4 Lego plates, so that was my initial constraint. I also wanted it to not be too tall, so that my 4-year-old son could comfortably build Lego on it.
I then took the design, and created a cut list in optiCutter. I used 4 types of sheets - 17mm green MDF, 4mm plywood, 12mm plywood, and 17mm plywood. The drawer slides were made from ipe wood. I cut everything on my table & mitre saws.
I assembled everything using wood glue mostly, with dado and rabbet joints.

#The 3D printed parts
I designed the drawer handles and Lego side plates in Fusion 360 and 3D printed them in my CR10S-Pro printer (I don't have a multicolor printer, so I had to print it in pieces and glue it together). Everything was designed to work with the Lego system, so you can attach real Lego bricks to it.
