Summary

some samples of head swaps, experimenting and adjusting. jet1 was experimental, works well prints good. jet2 was my need of narrow wide lip, works well prints easy 20min on my flashforge 5pro. I used pla plus, 20% infill,2 layer wall, 4 top and bottom layers.

Only need a magnet 12x3mm its plenty strong, original is 14x3mm
inspire me to make more additions.
