Summary

I had a hard time finding a replacement drive roller insert for my welder so like any good 3D printing hobbyist, I made one.
This version does not utilize the retainer clip like the original but uses an M4 bolt and printed washer to keep the drive roller in place.
There was an existing M4 thread on the shaft.
