The Roof Bolter: A machine designed to put steel bolts several feet long into the roof of a mine. These bolts lock the weaker layers of rock together and anchor it into a stronger layer such as limestone to keep it from falling on the miner's head.
Prints 100% supportless! The canopies, wheels and stand(props up the front end) fit inside the precut holes on the bolter body and can be glued or secured any way you like.
