Brick Round, Quarter 1 x 1 (LEGO® part 7532)

Posted by Elspeth De Montes

While we do not have a copy of LEGO® Pokémon 72153 Venusaur, Charizard and Blastoise to review, I was intrigued by one of the new elements that is exclusively found in this set (at least at the time of writing).

A few clicks later and I bought a handful of the new mould Brick Round, Quarter 1 x 1 on the secondary market, to take a closer look.

  • 12 x Brick Round, Quarter 1 x 1 in Medium Nougat (6553652 | 7532)

Hopefully more colours will appear soon, and in cheaper sets, surely.


Geometry



The new mould is one module wide and three plates high. The stud looks like it is closer to the edge than in other round plates and bricks, but this is just an illusion because of its small size.


It is the same as a 1x1 brick on two sides with a one-module radius curve that matches other 1x1 curves:

  • Tile Round 1 x 1 Quarter (25269)
  • Brick Round, Quarter 1 x 1 (7532)
  • Brick Round Curved 1 x 1 x 1 Quarter Dome (5848)
  • Brick Round Curved 1 x 1 x 1 1/3 Quarter Dome (1871)

  • Brick Round Curved 1 x 1 x 1 Quarter Dome (5848)
  • Brick Round Curved 1 x 1 x 1 1/3 Quarter Dome (1871)
  • Brick Curved 1 x 1 (7126)
The curve of the brick also matches when placed sideways, although the usefulness of this will vary depending on the gap you are filling, as there will be some SNOT-work required to make it align. 

  • Plate Round Corner 2 x 2 with 1 x 1 Cutout (79491)
  • Plate Round Corners 4 x 4 x 2/3 Circle with Reduced Knobs (66792)
  • Plate Round Corners 4 x 4 x 2/3 Circle with 2 x 2 Opening (79387)
  • Tile Round Corners 4 x 4 x 2/3 (68869)
Brick Round, Quarter 1 x 1 aligns with the curve on these plates that, up until now, did not have a brick to fit.

This is another plate we found with the same curve, which has only been in a few LEGO® Disney sets so far: Plate 4 x 4 with Rounded Corners, Pin Holes between Studs (7864).


Family

The new mould belongs in the 1x1 round brick family, but perhaps also the 1x1 curve family.  This line up shows it with various 1x1s:

  • Brick 1x1 (3005)
  • Brick Curved 1 x 1 (7126)
  • Brick Round Curved 1 x 1 x 1 Quarter Dome (5848)
  • Brick Round Curved 1 x 1 x 1 1/3 Quarter Dome (1871)
  • Brick Round 1x1 (3062)
  • Brick Round, Quarter 1 x 1 (7532)

It is now possible to have a quarter, half, three-quarters and full 2x2 round brick:

  • Brick Round, Quarter 1 x 1 (7532)
  • Brick Round, Half 1 x 2 (68013)
  • Brick Round, Half 1 x 2 (68013) plus Brick Round, Quarter 1 x 1(7532)
  • Brick Round 2 x 2 with Axle Hole (6143, 39223

Where fit?


Previously, matching a brick with Plate Round Corner 2 x 2 with 1 x 1 Cutout (79491) was unsatisfactory, such as the lime 2 x 2 macaroni above. The new mould can be used here – but be aware there's a limitation. With no stud on the plate, only the underside anti-stud can be used for attachment.


Now the complete wi-fi symbol is possible with both tiles and curved bricks!


The relatively new 2x2 curved plate (7904) can now be lined with with either tiles or bricks. When it first appeared, Tom took a closer look at the 2x2 quarter circle plate in set 11509 Flowering Cactus.

Tablescraps

It is now possible to create a satisfying little rounded box using the new brick to complete the corners.


Here a couple of little tablescraps to align other 1x1 curved elements – Brick Round Curved 1 x 1 x 1 1/3 Quarter Dome (1871) and  Brick Curved 1 x 1 (7126) – to the new mould.


The smaller curve can enable some nice repeating patterns.

 

It is possible to have your cake and eat a more reasonable slice, rather than gorging on a whole half.


Do you have any ideas for this new mould?

  1. Is there a functional reason why 79491 is missing a stud? If not then surely its days are numbered. Just one element to create now, the extended plate to go with the the 3x3 curved brick. Then is that it for basic curved elements, or will other combinations of extended/non-extended bricks, plates and times appear?

  2. How can we make LEGO add parts to PAB straight away in a standard set of 5-10 colors. This is another great part, but in an uncommon colour it will miss it's launch into standard usage.

    1. Realistically, we can't. PAB is a niche service compared to regular retail sets so would be unlikely to get the budget to have parts designed specifically for that. But I wouldn't be surprised to see this in other colors before long, you just need to be patient.

  3. "The stud looks like it is closer to the edge than in other round plates and bricks, but this is just an illusion because of its small size."
    Not sure what you mean by that, however it's obvious from your photos that the stud isn't rounded off as on the standard 2x2 round brick but full size and actually protrudes outside of the curve, which could possibly lead to some part collisions?

    1. Yeah it's quite possible that it would FIT inside a tube because of tolerances, but technically it shouldn't.
      I've came across a 1x1 PLATE version of this btw, in an old Kalos Blocks set. The stud is properly cut and there's not much problem of clutch power. However Kalos studs have a weird cross shape and that might be helping here.

      There's no possible illusion here, it's clearly a full stud & clearly protrudes, we even see its shadow.

  4. Maybe some day we can get plates to match the tiles and bricks
