M5 Adapter from Brass Nut to 5mm Threaded Rod

thingiverse

My Anet A8 B came with TR8x2 for the Z-axis, but I encountered some issues with wobbling and determined that the pitch was too high for optimal resolutions, so I decided to switch to 5mm threaded rod. On the photos you see a printed coupler, but it proved to be more visually appealing than functional due to the missing flex element. Currently, I'm using the simplest method between 5mm shaft and M5, which is a piece of PVC tube with an inner diameter of 4mm, similar to what's used for fish tanks. I'm really satisfied with this solution because it provides a nice centering effect and flexibility. This small adapter I created can be easily installed in place of the stock brass nut; the slot for the M5 nut is quite tight, so it works well when pulling the nut inside using a hex screw. It can be used with one or two M5 nuts per side.
