Many old games are filled with those purple regen buttons. Most of them have to be grouped with a model, but there are exceptions. Here are two examples, each suited for a different use.

Easy Regen
Apparently made by mccody, it is placed directly under Workspace and it simply uses a string to find the model to regen. Unlike most regen scripts, it actually checks whether it was a Humanoid that touched it.

Whether this is more messy or clean is debatable. You'd have to make sure there aren't any duplicate names.

Power regerator (sic)
Unlike most regen scripts, this 'regerator' regenerates every Model under Workspace. Also checks for Humanoid.

This one could be used to regenerate the whole map of the game. If you wanted to have something that doesn't get regenerated you'd have to parent it directly under Workspace, either without a container or within a Folder.
