For removing and installing Shimano Direct mount chainrings, new 12 speed style.
Print with 4 perimeters and 25% infill in PETG.
Print with the notches facing up and supports on.
Clamp the tool in a vise and rotate the crank to remove the lockring.
I was able to remove and install 2 chainrings before the notches broke off. Buy the proper aluminum tool if you need to do this often.
Similar to Park Tool LRT-4 and Shimano TL-FC41.
