These were an attempt at some 2 studs wide microscale grain hoppers... they feature some pretty intense snot techniques inside thats why i never built more than 4 of those ...that have been recently dismantled.
Nice. It's amazing that you can show more detail in a miniature model than a person can with a normal sized model. What piece is used for the wheels? I know it's not a 1x1 dot, but I can't tell what it is.
