Where to download a "multiple no collide" tool

[DEATH eVADER]

I loaded up onto a server where they had a tool, whereby you could select multiple objects, then these objects would then not collide with each other when you use secondary fire, but be fully interactive with everything else, including the player. This is especially useful if your trying to make a more robust contraption, but get annoyed when you hear those collision sounds when you require the contraption to be interactive with the player (i.e. you have to make a piece of the contraption, vehicle solid again).

It works well in principle, and I gave it a whirl, but unfortunately I could only find it on an unmoderated server, so I am hoping to download a version of the tool for my self.

I'm sure in the game, the tool was labelled as "multiple no collide" or "no collide- multiple", and I have checked garrysmod.org but came up empty handed. Any thought where I might download it from?
