My model tookway longerto make than i expected so ive kind of runshort on time to make a goodsite model and completed matrix. I had a few issues with makingthe model. I forgot to consider how much wider the papermache and laser cut pieces would make it and so some of the passage ways seem very narrow which wasnt helped by the model kind of warping with wet paper mache. It was hard to keep it in the right position so it would dry out right but i managed to get all the holes in the model fairly alighned. You can look through them and actually see through out the other end.
