Same problem here 🙁 At RS web I can buy M3.5 screws, but they dont have the nylock nuts. Are them critical? or I can use the regular nuts? Or is it better to drill the holes to use M4 screws and nylock nuts? Is not dangerous drilling the holes, so they became so close to the edge of some parts, and the part is weaker?
Thanks for any information about this issue. Im still collecting all the hardware and parts, and dont know what exactly to do.
EDIT: I also thought about using M3 screws and nylock nuts, instead of the M3.5, so I dont have to drill anything and the printed parts stay as the originals.
