The 3D Gear is a mower in the blade class of mow my lawn default shop.
The 3D Gear costs 100,000,000,000/100 Billion Trimmings, and can be bought in the default MML shop in the "blades" category.
Stats/Powers EditCan make you sprint fast for a few seconds. The 3D Gear, which is based off of the blade from Attack on Titan, is very thin and has a very small hitbox, thus making it troublesome to mow with, similar to the Plasma Hoe. It isn't recommended to mow with, since Omen is better.
The 3D gear is a reference to Attack on Titan, where the human characters would fight giants (titans) using these blades.
