This is a knuckle designed to protect the skid plate knuckle on an Minelab SDC2300 as it scrapes the ground. I designed it myself, it clips on/off so it is easily removed when worn. Protects a costly part of the machine.

3D printing settings I print with the base on the build plate, the base needs to be set to solid 100% infil for the base only to maximise wear, infil 30% for the rest to keep speed up, but with lots of walls to maximise strength to the clips. Printed with no supports, no brim in PETG, so they print in around 1.5 hours in 200um or 300um.
