Articulated excavator model

This is a pretty complex file I made a few years ago. I hope you will enjoy it, I printed it only once but it mostly worked. It is an excavator model to piece together.
each file is to print once, except the wheels (x4) and tracks (x2).
Good luck with your prints :)

To assemble the pistons, you have to insert them in the grooves perpendicular and then rotate them and click them in place into the next arm.
