Simple Prusa z-wobble stabilizer
thingiverse
There are many fantastic Z-screw accessories available, but this one takes the cake in terms of simplicity. Just print it off and slide it into the z-screw hole at the top of the frame, making sure it fits snugly on the screw and rotates with a bit of friction in the socket. If it binds, give it a quick sanding to smooth things out. While it's not as sturdy as one with bearings, this little guy does its job remarkably well, reducing play to almost zero. This design is specifically tailored for Hesine Prusa i3 printers, but the same principle should work beautifully on any printer that features a hole in the top of the frame for the z-screw.
