Optical filament sensor with Teflon tubes to reduce friction. The springs have a diameter of 4 and a length of 25mm, it is important that they have little force to reduce the friction of the filament to the maximum. A 3D model of the assembly is included to modify housings for springs in case you want to change springs. The springs that I have used are pen springs that do not have much force. https://youtu.be/Y5apX_JWutw
