Random laser cutting projects

I was snooping around on the internet and i came across a very nice project created by Jack Carter called the "Lasercut RC Jagdtiger". It's an awesome project but I have many questions to ask the person who built this project. Here are the dimensions

Length

40 cm for the hull, 54 cm with the cannon

Width

21 cm

Height

16 cm

I like this project because it's something different and it also has a better look. It's something i've never seem before and it is very unique. There are a lot of small pieces and when making this project everything would have to be very very perfect to fit.
