This work is built for the competition "Battle of the Masters in 2016 cube" on bricker.ru site. The main conditions of the competition was to fit the model in size 16x16x16 stud and a ban on the use of the plates. Participants were few, decent work, but as a representative of Technic, I was there alone ... and took the 3rd place.

Very nice! I also like the fact that it is minifig sized. Almost looks like a FIRST LEGO League model ;)
