Sphere

Ever since I got the "The Ultimate LEGO Book," I have wanted to make a sphere like the one shown by master builders.

A few years ago I tried to make a small one but it did not turn out that well (if I can find photos of it I will try to post it sometime). A few days ago I went online to see if I could find instructions for one.

I cam up empty handed since most of the ones I found online where not as detailed or required angle plates to achieve a sphere like shape. Nothing using just "normal" plates and bricks.

Over the weekend I pulled out the book and examined the photo that was included and created my own version. After about 13 hours (over 3 days) of building it was finished.

Weighs around 4.7 pounds
32 studs across
26.33 bricks high (79 plates)

Wedged Cube DD

I created the wedged cube model in the digital designer. Getting it would cost $5.54. Seems a little expensive for 22 pieces. I'll have to try getting one sometime.

Click on the LEGO Factory Creations on the side to view it and the other models I have uploaded. (NOTE: not yet approved as of this posting, so this will not be listed)

Wedged Cube


I initially created 8 corners using some wedge plates thinking of making a large cube. I was trying to come up with a way to connect them nicely and stumbled upon the smaller cube below that uses just 4.


A closeup of the corner's "inside." The build pictures below create the cube differently since it seemed easier to construct it that way rather than trying to connect four of these corner pieces together.


All the pieces used for this model, just three types.


Two wedges and a 2x2 plate make up each side of the cube.


Place a wedge on the 2x2 plate as shown.


Put the other wedge next to the first.


Make 5 more of these for a total of 6.


Turn over three of the sides and place connector bricks as shown.


Assembly these three sides to form half of the cube.


Carefully add two more. It might be slightly tricky to get good, solid connections between the bricks. If you take your time and make adjustments it will eventually work out.

Hinged Cube

Here is a simple cube that I created with some hinge plates. Not sure how I might use this, will probably try some different variations.


Pieces that make up the model, just 3 unique parts. Arranged as they should be assembled.


Parts put together except for one connection.


Completed cube.

Waves - 4 and 6

I was playing around with some pieces that are used in one of the airplane sets to create a "wavy" looking enclosed structure. Have not really thought of anything more complex to do with this model yet.


4 waves joined together to make a square.


6 waves form a rectangle.


Adjust the waves, and get more of a circle.

Hexa-base

I was looking at some different pieces and noticed that I could combine six of R2-D2's legs to make a hexagon type structure. Using this as a base, I made a few different structures.


The base hexagon structure.


A box.


Change around the box, and you get a snow flake.


Using some "wings," create a cone. I had to use 3 pairs since I did not have 6 of one side.


Again, flip around the wings and make a star. This is my favorite of these models. I have been trying to figure out a larger creation to integrate this in, but so far have not come up with anything.
