How to make a New Hashima style technic cube

 

Hey brick fans!  Welcome back to another tutorial!

Today, we will build a technic cube, New Hashima style!  New Hashima is a huge Lego cyberpunk city with many collaborators building their own unique sections and adding them to the collective.

Here's the history behind New Hashima with a lot of pictures of the cool setup: https://bricknerd.com/home/the-story-of-new-hashima-how-the-colossal-lego-cyberpunk-city-came-to-be-7-17-23

The underlying structure of the Cyberpunk style city is supported by a series of large cubes that are made primarily of technic bricks and technic pins.  Once assembled, they provide the framework and the support for the towering creations.

Here are some screen shots I found on Flikr (just google New Hashima cubes to see more examples).



Initially the instructions to create the cube were posted on Simon Liu's flikr page, but then they were deleted.

Only to resurface as a link on a Eurobricks forum:  https://uofi.app.box.com/s/ykq9ilqy7cgfljxqkjdcc5hlgyzvyy46

I've taken a look at them and have tried to create a version that is a bit simpler and uses less parts, hopefully while achieving the same objective of modular strength and support.  If my setup works, I will create a larger refined version of the New Hashima style cube.   


My plan is to incorporate the usage of the cubes into my growing  Lumibricks Cyberpunk city, perhaps under the Lumibricks Izakaya, because it's looking kind of small next to the other towers.

Here's my parts list

standard technic pins (x8)
longer technic pins (x16)
2x8 plates (x16)
2x2 plates (x16)
2x4 plates (x8)
1x16 technic bricks (x24)
1x2 technic brick (x8)
2x2 tiles (x8)

Using these parts, it will make a cube that is 18 studs wide, 18 studs deep and 16 studs high.  You can save some money by using Lego compatible parts as I've done here.









Here's my method to create the cube


Step 1.  Make the beams and assemble them into squares.

Take one of the standard technic pins and insert it into the last hole of a 1x16 technic brick.  Now, take two of the longer technic pins and insert them into the third and fifth hole.  Take another 1x16 technic brick and snap it over the other.

Repeat the above steps eight times and assemble four of the beams  to make a square as shown in the picture below.

Now I'm going to secure the beams to each other by attaching a 2x4 plate to each of the corners.

Do the above two steps twice and you will have two squares.

Flip the squares over.  One of the squares will be the bottom of the cube and the other will be the top.

Now, take the pieces show above to make a support beam.  Put two 1x16 technic beams together and press a 2x2 tile at each end.  Then press together two 2x2 plates and place them on the underside of the technic beam, at both ends.  Then attach the 1x2 technic brick to the plates.

Repeat the process three more time and you will have 4 assembled support beams.

Take one of the support beams and place it 90 degrees to the bottom square, as shown above.  Press it into the protruding technic pins to lock it in.


Take the top square and lock it into the technic pins as well.

Now, repeat the process three more times for the remainder of the supporting beams.




To finish off the cube, add some 2x8 plates at each top corner of the cube. 
Take 4 more 2x8 plates and fill in the rest.

Repeat the process of applying the 2x8 plates to the bottom of the cube.


Alright, the small cube (18x18x16 )was a test just to validate the design.  I'm probably going to need to double the amount of 1x16 technic bricks, add a few more technic pins , and use extra 2x4 or 2x8 plates to make a full sized cube to match the New Hashima standard.

Ok, thanks for staying to the end of my blog post!  Let me know if you plan on using the New Hashima style cube in your city!  See you in my next one, bye!
