Upgrade set cannon for moving tank

cults3d

Upgrade set for earlier design "Tank with moving tracks and turret". Upgrade your tank and shoot rockets and cannonballs. The cannon also works without the tank, so also interesting to download if you are only into shooting stuff. Note: A metal coil spring is also needed to operate the cannon itself. This is of course not included. But when you print and create it you have a nice object to play with.
