use estos acoples en una impresora 3d que comstrui para disminuir el nivel de ruido y la vibracion genedada por los motores del eje x y y, y si los reducen bastante,pero no puedo ponerle 5 estrellas y eso es debido a que todo el conjunto del los acoples vienen descentrados, me tomo horas tratando de centrar las partes de cada acople y descubri que con algunos suplementos hechos de cinta termica y cinta de enmascarar y teflon logre mejorar la alineacion.dejo unas imagenes para darse cuenta de esto.

I got these because I’m planning on building a DIY 3D printer. These are an absolute must in my opinion for any 3D printer to prevent wear issues and the like. Highly recommended

Easy to install. Shese have a nice firm spider and tight fit to avoid any potential backlash issues.
