Chainring Tool for Shimano Direct Mount

Tool for removing and installing Shimano Direct mount chainrings.I printed mine in ABS in 100% infill and after one use I dont see any damage, but the original creator - Adanac was printing those in PETG with 4 perimeters and at least 25% infill.Print with the notches facing up.Clamp the tool in a vise and rotate the crank to remove the lockring or use a 48mm wrench .Since I use this tool in a wise I have changed the hex nut size to a much bigger OD of 48mm. This removes the need for supports. Also added 6 holes for more tool strenght.
