Building the Big Ben 3D Puzzle

I haven't put a puzzle together in years and I've been tempted to try a 3D one for a long while, so I thought I'd finally try one. 🙂 If you don't mind fiddly bits and the structure possibly being a bit of a pain to put together, this is quite good. I do like the lights as well.
