Sorry, I don't have any examples because I don't use them. I first came to this conclusion when I tried to buy a simple cutting wheel with just a hole for an arbor at Home Depot and they had no such thing. All they had on their shelves at my local HD were disks that were threaded for DeWalts.
So if I am mistaken I am sorry, but it seems to me that ANY ATTACHMENT should be pretty much universal AND CHEAPER than something that is specially made for a specific brand. Proprietary products ARE ALWAYS more expensive than the same quality universal product.
The universal type is what I CURRENTLY use for Milwaukee, HF, and Skil angle grinders. And they are made by a large number of quality manufacturers, but I can't say that 3m makes them.

I've used quite a few industrial grinders, from old Black & Decker to Dewalt to Bosch, to Makita, etc from 4.5" up to the biggest B&D Wildcat they used to make. Have used all of them with grinding disks, cutoff wheels, wire wheels, wire cups, custom designed and manufactured refacing tools, mixing sticks, etc.
When a person knows what model to buy (not the ones that Home Despot or Blows sells) they are all compatible and interchangable. We weren't about to stock different grinder disks just because we had a couple of each manufacturer.
Most of the disks that screw onto the mandrel will fit
any angle grinder that uses a jam nut to hold the disk on. And most any jam nut will thread onto just about any grinder. When going to purchase a grinder, just look at the mandrel. If its threaded and comes with a jam nut, you can use any disk currently on the market for that size of grinder.
Prime example; the Dewalt I bought 5 years ago came with the jam nut and the wrench to take it on and off (not like you need it if you know what you are doing), but it just sits in the drawer along with the wrenches and mandrels for the die grinders since I'm still burning up the old stock of wheels we bought before the company was sold off.
Edit: To the OP; I much prefer the slimmer body grinders with the toggle switch that you have to hold with your fingers, such as
this Dewalt model (clicky). The thumb switch ones that lock on aren't bad if you're used to using angle grinders and are comfortable around them. I rarely use mine with the handle on it, as there is more then enough room for both hands on the body and I can get more control that way. Bigger then a 5" wheel is when it comes time for either the loop handle or side handle, as they can get away from you FAST. Have many a pair of Carhartts with shredded up double knees from those big Wildcats with a cupbrush getting away from me.
