LEGO® part 7037: Brick 2x2x⅔ Half Circle with 2 Studs and Curved Top

Today we have a mini-parts festival all in one article! Three team members have turned their eyes to a  mould introduced back in January 2025: Brick Curved 2 x 2 with Curved Front, 2 Studs (7037). Tom Loftus treats us with a quick look at the geometry and connection points, and Kevin J. Walter and Eero Okkonen experiment with some creations of their own.

Initially exclusive to tan (6525418) in LEGO® Creator set 31162 Cute Bunny, part 7037 is slowly starting to show up in other colours:

• Dark tan (6564888) – Used as the lower jaw on LEGO® Jurassic World™ Rebirth 76970 Baby Dinosaur Dolores Aquilops, reviewed by Kev Levell
• Light bluish grey (6539782) – in LEGO Creator 31171 Wild Animals: Majestic Rhino with Birds; and LEGO® Disney 43279 WALL-E and EVE
• White (6554300) – Used in the bow of LEGO® One Piece 75639 The Going Merry Pirate Ship, reviewed by Thomas Jenkins; and in LEGO® Star Wars™ 75432 V-19 Torrent Starfighter

Presumably there will be more appearances to come, so let's take a closer look at this strange addition to the curved slope family.

Geometry

Rounded elements of 2-module diameter align perfectly with the slope's front edge. The combo shown on the right is especially satisfying since the slope's lower section has the same footprint as the 1 x 2 half round brick (68013).

The top curvature is less common, but still matches a handful of existing elements:

From left to right:

• Brick Curved 2 x 2 x 2/3 Two Studs and Curved Slope End (47457)
• Slope Curved 2 x 2 with Stud Notch (Left 5095 & Right 5093) 
• Wedge Curved 1 x 2 x 2/3 No Studs, Wing End (47458)

I'm not sure that last combo has any practical applications but it's very pleasing nonetheless!

Here are some similar shapely elements that feature 1 x 2 plate sized cut-outs:

• Plate Special 2 x 3 with Rocks (27261)
• Slope Curved 2 x 2 with Stud Notches (66956)

On the right is a not-so-similar shapely element: Wedge Curved 4 x 2 x 1 1/3 with 1 x 4 Base (93589). In my mind's eye, the new slope had more in common with this F1 car nose, but in reality? Hmmm, not so much. I still think there's some intangible kinship going on though.

Less uncertain is 7037's potential for architectural details – stack a few together and you realise it's a roof tile, no question!

Many newer parts seem to feature jumped anti-studs, and 7037 is no exception. "Nail rails" like this are an economical way to add strength to a mould while boosting the number of connection points.

The part's central anti-stud holder combined with its rounded front make this technique using a 3 x 3 'plus plate' (15397) possible. Granted, the same configuration works with other elements like these 1 x 2 half round tiles (1748, pictured above right), but they hardly compare to the abundance of connection points that 7037 provides.

Tom Loftus' creations

With a couple of studs, the underside of the slope becomes a toothy grin, just like my Donkey Kong feet (3560) heads! I can totally picture these guys together in some Indiana Jones-style temple.

Speaking of temples...

I was pleased with this unlikely (and illegal) connection using a 2x4 spoiler with Handle (98834)... until I realised it works just as well with existing 2x2 round parts with anti-studs.

It did, however, spark this little build:

The seed part might be a bit perfunctory but I'm still pleased with how this idyllic chain of islands turned out – especially the little sailboats made with minifigure epaulettes (2526). 

 

Kevin J. Walter's creations

The mass of tan parts in LEGO Creator 31162 Cute Bunny made me wanted to play around with the ever-popular 1998–2003 theme LEGO® Adventurers. 

This might be caused by the fact that Ancient Egypt has drawn my attention and passion for several years now – be it within LEGO building, or in general. 

Enjoy the following tablescrap MOCs – or, to put it in terms of LEGO Adventurers – Ancient Egyptian relics buried in the desert!

 

When I started my first Egyptian MOCs back in 2020, the Sphinx was one of the first designs I did digitally.

Naturally, my first MOC for this article was a Sphinx, with feline body and human head, wearing the typical Nemes headscarf. The new 7037 curved brick made an excellent hind leg. 

I also made the second typical Sphinx with the shape and head of a ram. These were placed, for instance, on the left and right sides of the great processional way between the temples of Luxor and Karnak. 

Another early focus of my LEGO Egypt work was how to build temples... and therefore, significant amounts of columns. I experimented with many parts, trying to cover the various shapes of capitals found on top of Egyptian columns, from Lotus to Hathor Head. 

With this new curved part (which I had ordered in bulk for myself via Pick A Brick before LEGO sent me a copy of Cute Bunny), I tried to capture the look and aesthetic of another capital type: the Palm.

While I liked the outcome with the new part on the Palm capital, I still prefer the my solution using LEGO® DUPLO® cupcake parts instead, which is in a larger MOC I have been working on for quite some time now.

The last idea I had for part 7037 was to use it as some kind of face plate of an statue. The result was this relic of a statue of Ramses II, inspired by their real life counterparts of the Abu Simbel temple. 

 

 

Eero Okkonen's creations

For me, LEGO Creator 31162 Cute Bunny feels like an ideal "MOC-fodder" set: it has plenty of elegantly shaped pieces, it is affordable, and has no distracting things like minifigures. The parts selection is obviously made for characters or creatures – my main MOC subjects – but it's nonetheless tabula rasa of open possibilities.

Before starting this model, I had a relatively clear idea what I was aiming for. Only the final scale remained a mystery. 

The human depicted here is no-one in particular, but one stylistic point of departure was the Pohjan Neito sculpture by Emil Vikström (1913) in my hometown, Tampere; I pass it often during my evening walks. 

This uses many parts from the cute bunny, but also from other recent sets with curved tan parts. I think it is a love letter to new (and some old) pieces in this colour; a trial of shaping and sculpting in monochrome. 

I used the seed part 7037 in the middle of it, as the apex of the nose. I think it captures the shape nicely, but the studs were problematic, and the 1x2 half-round tile feels a bit like a compromise. I rather like the nostrils, though, both made using a single Brick Curved 1 x 4 x 1 Rounded Ends (6445992 | 4045). That doesn't come in the bunny, but is a good example of other recent tan parts I mentioned. I always think of it as a Donkey Kong lip, though – and indeed, I also used it here as a bottom lip. 

Similar in shape, I used Brick Curved 2 x 2 x 1 1/3 Curved Top, Corner (6486890 | 67810) as the eyeballs, slightly visible behind the eyelids. Initially, they made up the bunny's forehead.

 
A special mention goes to the two quarter-circle curved sloped elements, 2x2 (6525416 | 5852) and 3x3 (6404615 | 76797). I really enjoy using both of them – and I have an inkling that the smaller one in particular will be revolutionary in eliminating irritating clear-cut edges in character models. Here, I used 4 of them – 2 from both of the bunnies I got; a pair makes up the jaw tip, while the other pair are used just under the ears, hiding a distracting antistud. With 2 bunnies, I had 20 of the 3x3 version to play with, and I used them throughout the model.

The hair is made using a frame of 4 trans-clear Bar Curved with Axle End and 1 x 1 Round Plate (6510119 | 4042), and the segments are connected using clip plates. I gave the model a bun so the aerodynamic hair makes more sense. The mundane hair style keeps the focus on the sculpting of the face, which was the emphasis of this model.
