Lock rings for smooth rods on printer

thingiverse

An essential component used by DIYers and hobbyists alike, an M8 nut modified into a locking mechanism secures 8mm smooth rods in place with remarkable ease. On my P3 steel build, I noticed a significant lack of friction preventing the rods from shifting longitudinally; however, this modified nut solved that issue seamlessly. Specifically designed for use on the X-axis, these lock nuts could also be applied to Y and Z axes, but I opted for alternative solutions there instead. Their ease of usage and swift adjustability make them an ideal addition to any build. Instructions Using a drill with a diameter of 8.1mm, remove the threads from an M8 nut while securely holding it with either a wrench or machine vice for optimal safety. Drill a 2.5mm hole through one face. Subsequently, thread this newly created hole with an M3 tap. Insert an M3 bolt or grub screw into the hole. The nut's faces may need slight adjustments using files to ensure it is flush with the surface.
