Initially I was just going to put the words 3D Motion on the dolly on the tracks, but I don't think that it would be clear enough to people that it meant 3D track motion ( Clever little Ideas to me, are just usually confusing to the masses

).
glad you like it.
There's detailed modeling on the wheels bolts, like a nut to screw into, and a little extra bump on the tip of the opposite end that no-one sees and was almost entirely pointless to spend the time doing, plus a locking handle on the dolly handle, and a separated spinning portion of the handle. Just pointless stuff based on final results and the small overall size, but I wasn't sure exactly what I was going to do with it while making it.
