About this 3D model

I found with Lawsys MK5 jigsaw replacement extruder setup that my extruder would pull forward and back when the filament was retracted. This modified clip holds the peek barrel in a bit better and prevents this movement. The only difference in the two versions are the v2 one has a cut-out to reduce contact with the peek and allow a bit of air around it as I'm not sure how hot it will get if it's running for hours. Either should work the same.
