Endcap An endcap is a small protective component used in 3D printers to cover the ends of rods, extrusions, or other structural parts. It serves multiple purposes, including preventing damage to exposed ends, reducing noise or vibration, and enhancing the printer’s aesthetics. Endcaps are often made of plastic or rubber and can be 3D printed or purchased as aftermarket accessories. They are particularly useful for maintaining safety by covering sharp edges and providing a finished appearance to open-frame printers. While endcaps may seem minor, they contribute to the overall durability, usability, and professionalism of a 3D printer setup. |
