I see that this popped up on HNQ, so I wanted to expand on shoover's excellent answer with a build showing one way that this could be put together for folks that may not be as familiar with LEGO elements as the Bricks community.
As was already pointed out, the key element here is the 2x2 turntable base without a turntable attached:
Here's how you might ...
The wall behind the shelving unit is not a standard wall built with regular LEGO bricks, but a panel, which is hollow on one side.
The parts that are sticking out at the back of the bookshelf are accommodated by the hollow of the panel.
My guess is that you attached the panel backwards with the flat side facing in, instead of out. Look at Page 37/Step 48 ...
It's kinda chunky, but the best I can come up with is 42446 + 2555:
It would leave a half-plate gap on one side if they only have 1 holster though, but at-least you keep the regular minifig legs.
NOTE: This probably wouldn't be considered a "legal" connection, due to the semi-octagonal shape of the leg connectors. It's definitely possible to put ...
The easiest way to do this would be to use a motor with a high speed (or gear up a lower speed motor) and then attach one of the larger propeller elements to it. You can probably build a custom prop, but it might be challenging to build something with the proper blade angle while keeping it light and strong enough to not break apart when rotating quickly.
Before I attempt to come up with an answer, let me share how I think through problems like this, as it might make it easier for others to solve problems like this in the future.
We can see that the gap itself is 30 LDU, as modules are 20 LDU, so 1.5 modules is 30 LDU. Some quick rules of thumb:
Multiples of 20 LDU can be made with regular bricks ...
From this picture and this one, you can see that the framing of the windows is formed by Turntable 2 x 2 Plate, Base in black.
For the colored areas (the "stained glass"), you have a couple of options:
You could use different "Trans-X" colored Plate, Round 1 x 1 inserted into the back, but you'll need some trans-clear plates to back them up so the ...
The answer depends on your definition of "legal". In the strictest sense, it means "can be used in official LEGO sets", and in this case, this is definitely not legal, as the axle is not designed to bend that way, unlike the many various hinge and joint pieces.
On the other hand, "legal" might mean "does not cause damage to the pieces", and in this sense it ...
The review over at Brickset mentions this exact modification:
Pearl gold windows are fixed inside each gunport, preventing the deployment of cannons. While this seems slightly odd, the lattices can be removed and replaced with cannons, as demonstrated here. I appreciate these options but some furniture must be removed from inside to create enough space ...
Donny Chen made a LEGO piano that I believe is just large enough to play. Details are available on LEGO Ideas. You can watch him show it off in a video from Brickvention 2019. He has it motorized in that video.
From your comments, it sounds like you are interested in not simply having a piano with keys that can move, but one that actually emits proper sound....
Perhaps something like this using 1x4 arches could work?
This does work out to being 2 modules too wide for 1:1 scale with a GameCube, but the trade-off in accuracy may be worth it to you to get the round ports. It appears to be only 1 module wider than your current design.
Here's more detail of the build steps:
Lego bricks are not sized similarly in each dimension. The height to width ratio of a brick is 6:5, which means that 2 bricks stacked on top of each other with their studs up are 6 plates high, but the same 2 bricks stacked on top of each other on their sides (studs facing sideways) are only 5 plates high. Said differently, bricks placed sideways (studs to ...
There is this monstrosity as an example on the internet, which proves that you can work with proper metal strings. But your biggest enemy will be the huge tension everything is under. There is a reason that proper pianos have steel frames. As you only want one or two octaves, you can probably do without reinforcing the frame, but wherever the strings ...
The best I could find in terms of instructions for 9335 is this page, which seem to contain all the prints included in the set. However Lunar lander is missing. It looks like one of those "inspiration" sets LEGO used to include in the old days. Looking at the pictures I found they are reasonable quality and model doesn't contain too many parts. So ...
Here are some Ideas i came up with. I added some of your suggestions for comparrison.
Mounted on top of the plate:
11458, 32013, 2780
Mounted below the plate:
32000, 32013, 2780
3701, 32013, 2780
From LEGO point of view this definitely would be illegal to assemble such axle with particular frame since you cannot build and then take this apart without bending the axle.
But from AFOL's point of view this could be a doable solution for a MOC if there is a real need. There's plenty of space to bend the axle and it won't get damaged.
this way it can open and close
Blue = 4276 Hinge Plate 1 x 2 with 2 Fingers
Yellow = 4275 Hinge Plate 1 x 2 with 3 Fingers
LightBlue = Plate 2 x 4
White = Plate 2 x 2
Pink = Plate 1 x 4
Light Bluish Gray = Plate 1 x 3
Yellowish Green = Plate 1 x 2
Red = Tile 2 x 2
Green = Tile 1 x 4
If you'd like to keep your build studs up and avoid dealing with the 6:5 ratio, you could try to use Plate, Modified 1 x 2 with Arm Up with the already mentioned Brick, Modified 1 x 2 x 5 with Groove, as the 3.18 mm bar will slide in the groove just fine.
Another option would be to keep the rest of the elevator car studs up, and only turn sideways for a few ...
I am still waiting for the bricklink delivery with 27448 tiles that Alex suggested in one comment of his answer. Therefore, I tried a less subtle solution:
This is the starting point: A DUPLO pig that needs to be put directly on LEGO pieces.
I decided to cut a DUPLO piece to regular LEGO size. A DUPLO 2x2 brick was converted to a ...
... 4x4 tile, ...
Calculations / Pre-process
I started off by guessing that your MOCs are about 7 minifigs tall. If a minifig is 4 bricks tall that makes the overall height 28 bricks tall.
It looks like the tallest buildings are about 20 stories tall and the shorter buildings are 5 stories tall.
So you're looking at 4 plates or 5 plates per floor to build these. 4 plates ...
You can attach couple of half bushes or full bushes on inner side of the axle near Technic beam like on the other side you have done with a gear. If axle is still trying to slide - fill in the entire inner axle part with bushes.
Here is picture of suggested fix. Here you can see extra half bushes added to fix the axle the same way gear fix the other axle ...
It looks like LEGO did not intend to make Shuttle attachable to ISS despite the statement. At least not with a stud-on-stud connection like the set is designed right now.
As seen in picture below, Shuttle is docked using a connection port inside storage bay with its doors open. Not sure if it is possible to replicate opened doors in scale Shuttle and ISS ...
There is a bit of a challenge with a geometry. LEGO doesn't produce much symmetrical hinges, otherwise they would be out of system. I could think of the following one piece you could achieve a close result - Hinge Plate 2 x 4 with Pin Hole and 3 Holes - Top. It comes in White color as well, so you could incorporate in your layer of white plates.
Here's a ...
According to this article, the turning is supposed to function via a
wheel on the bottom that while the car moves forward stays straight but that once the car moves backward moves a little to the side and forces the car to turn.
If correctly built, it should look like this:
A bit later the article offers a few tips on troubleshooting, among which there ...
