I had built a Bride and Groom for one individual (this was not my original design, it was sent to me as a single digital picture, and I reconstructed it). Other people had also sent various emails to me because either they were getting married or they had friends who were getting married and someone involved was a big fan of LEGO.
I had actually designed plans of construction for a large LEGO cake over a year ago, but it had never been fully built. With the apparent interest in wedding related LEGO models, I decided to go ahead and build such a cake so that the next time someone asks for something, I'll have completed this and can reply, "if you want this, I can ship it immediately".
I went with a pretty classic design for the cake (not that I am, by any means, an expert of wedding cakes). It has three tiers. While superficially it appears to be all white, the majority of the model is actually yellow. This is because I designed the cake so that it could be disassembled into pieces (or 'slices') of cake... and the cake is yellow with white icing.
The idea is that the bottom two tiers of the cake are comprised of 124 slices of LEGO cake. These slices, while obviously not edible, could be distributed to guests of the bride and groom as souvenirs... everyone would get their own little LEGO memento of the happy day.
The top tier (the smallest one), has a bride and groom mini-figure display and does not deconstruct... it would be a single piece that would be kept by the newlyweds.
The building of the cake went pretty much according to plan. Man, did it use a bunch of small pieces. In order to use up some of my many lesser sized bricks I tried to use as many 1x2s and such as possible. In the end I think I used about 3,000 yellow 1x2s as well as many other sizes in both yellow and white.
And, boy, does that make a *heavy* cake. This thing is SOLID. The bottom tier is 48 studs in diameter (15 inches), the second tier 32 studs, and the top pieces 16 studs. Underneath the largest tier is a large gray base plate outfitted with plenty of 2x2 white smooth tiles. The edges of the 'plate' have a few white plates (with studs), and these act to hold the outer 'ring' of slices in place. A similar scheme was used on a platform holding the second tier of slices.
One might be surprised at how popular LEGO wedding items are. They are probably the most commonly requested theme I get as a craftsman. In addition to the items mentioned in the text to the left, I have also fashioned these things for people at various times:
Who knew so many lovebirds also loved LEGO?
Birthday Cakes are also available if that's your celebration.
