## Meta Lego Storage

In need of a way to organize and store my Lego obsession, I made a bunch of acrylic boxes which not only hold Legos, but also stack and interlock similarly:

Each brick box holds 64+ of the same-shape piece. So the 1×1 box will hold 64 1×1 bricks, and the 2×2 holds 64 2×2 bricks. The larger ones hold a few more due to how the sizing works out. The 1×1 box is 40mm per side (external dimensions).

I posted the patterns on Thingiverse should anyone wish to make their own. No, I'm not going to make and sell them. They're time consuming to make, and plus I'm pretty sure Lego would sue me. If you don't have access to a laser cutter, I'd suggest using a service like Ponoko.

The patterns were generated in OpenSCAD using the following code. Change "rows" and "cols" to get the lego size you desire. By the way, I’m teaching a class on OpenSCAD in Brooklyn next weekend!

fundamental_unit = 0.8; thickness =3; h_pitch = 10; v_pitch = 12; tform = 5; knob = fundamental_unit*h_pitch*tform; module side(rows){ lwidth = rows*fundamental_unit*h_pitch*tform; lheight = v_pitch*fundamental_unit*tform; difference() { square(size=[lwidth, lheight]); translate(v=[10,0,0]) square(size=[lwidth-20,thickness]); translate(v=[10,lheight-thickness,0]) square(size=[lwidth-20,thickness]); square(size=[thickness, 10]); translate(v=[0,lheight-10]) square(size=[thickness, 10]); translate(v=[lwidth-thickness,10]) square(size=[thickness, lheight-20]); } } module top(rows,cols,holes){ lwidth = rows*fundamental_unit*h_pitch*tform; llength = cols*fundamental_unit*h_pitch*tform; difference(){ square(size=[lwidth,llength]); square(size=[thickness,10]); square(size=[10,thickness]); translate(v=[lwidth,0,0]) square(size=[-thickness,10]); translate(v=[lwidth,0,0]) square(size=[-10,thickness]); translate(v=[lwidth,llength]) square(size=[-10,-thickness]); translate(v=[lwidth,llength]) square(size=[-thickness,-10]); translate(v=[0,llength]) square(size=[10,-thickness]); translate(v=[0,llength]) square(size=[thickness,-10]); if(holes==true){ for (i = [1:cols]){ for (j=[1:rows]){ translate(v=[j*knob-knob/2,i*knob-(fundamental_unit*h_pitch*tform)/2,0]) circle(r=fundamental_unit*6*tform/2); } } } } } rows = 2; cols = 4; h_spacing = rows*fundamental_unit*h_pitch*tform+10; l_spacing = cols*fundamental_unit*h_pitch*tform+10; v_spacing = fundamental_unit*v_pitch*tform+10; side(rows); translate(v=[ rows*fundamental_unit*h_pitch*tform+10,0,0]) side(rows); translate(v=[0,v_spacing]) side(cols); translate(v=[ cols*fundamental_unit*h_pitch*tform+10,v_spacing]) side(cols); translate(v=[0,2*v_spacing]) top(rows,cols,true); translate(v=[ rows*fundamental_unit*h_pitch*tform+10,2*v_spacing]) top(rows,cols,false);

In the next batch I'm going to make the nubs a little smaller than the holes. They work now, but it's a bit fiddly getting everything to line up just so. A little more forgiveness would be nice. Also, OpenSCAD does strange things with circles. Rather than simply write a circle in the DXF, it represents it as a bunch of line segments. I’m not sure if there’s a way around this, but it’s marginally irritating.

You can download a .dxf for a few different box sizes on Thingiverse.

I’ve also created a Flickr Collection for my various Lego stuff.

This is totally rad.

Your creativity is amazing

You will of course now need a larger lego-shaped container to contain your smaller lego-containing lego containers. This will continue until you have a single, coffin-sized lego chest, containing ln(N)/K levels of lego containment (where N is your total lego count, and K is the number of legos that can fit in each container). This will satisfy my OCD, at least.

I thought of the same meta-meta-container idea as @phookyThe OCD, but I don’t think it would work. All of the normal Lego blocks inter-operate, you can have small ones connect to bigger ones. Its a very clever design. But a container needs to have sized and tops with finite width, so each larger box would have to be larger, so they would not properly connect to make, say, a wall of boxes of Legos

super cool

I love these! It’s possible I play with my son’s Legos more often and enthusiastically than he does. (Why didn’t I when I was younger? Something to do with being a girl child well supplied with dolls instead.)

If you ever change your mind about mass production…I know, copyright infringement is such an ugly phrase!
