Hello @nacho87

I highly recommend to get stepper with integrated lead screws because those flexible couplers are going to add flex in the Z motion which is not a good idea. This is why I prefer to not support those. However, check this video on how to modify the Bear X axis: https://www.youtube.com/watch?v=N1Hm1EWMIEo

For the brass nuts, check the optional parts from the community here (two latest in the table) : https://guides.bear-lab.com/Wiki/community_optional_parts?revisionid=HEAD#Section_Bear_Extruder_and_X_Axis

I hope those links will help you :)
