I printed these 4 and they look amazing. I will replace the original ones because one of them is broke.
The questions I have are the followed:

  • Do I need new 4mm screws or can I use the original ones?
  • How many nuts do I need? 2 for each side to lock the screw against rotating while I'm level the bed?
  • Do I need secured nuts? 1 or 2? Or is a nor Mal 4mm nut enough?
    That I will need a washer is known.

Thanks for your help!
