for 3D Touch is a self-leveling sensor for 3D printers that accurately measures the inclination of the printing surface. It can greatly improve the printing accuracy of your 3D printer. for 3D Touch is simple, smart and precise. It can be used with almost any type of bed material such as glass, wood, metal and more. The main functions and controls of for 3D Touch are the same as most self-leveling sensors, so for 3D Touch can be used on almost all 3D printer control boards. By using progressively designed solenoids and hall sensors, for 3DTouch can integrate high precision in such a simple structure. color: White Material: ABS Package Contents: 1 x sensor 1 x 200mm cable 1 x 1000mm cable 2 x M3 nuts 1 x XH2.54mm 2 pin terminal 1 x XH2.54mm 3-pin terminal 1 x Continuous winding terminal Only the above package content, other products are not included.
