This is a bed leveling wheel for the FLSUN i3 plus or C plus. The stupid little wing nuts (or if you read the instructions for building this "butterfly nuts") that come with it are hard to adjust and annoying. These make the bed leveling screws as smooth as butter when making adjustments. These wheels a a bit over 2 inches in diameter. You will need to print 4 of them and will need some M3 nuts. These print with a sacrificial bridge in the screw hole. it is 1 layer thick (when printing in .3) and will need to be poked out with a small screwdriver or m3 screw. The tolerances on this part were fairly tight when I printed them. You will need to pull the nut into the wheel using an m3 screw and a wingnut threaded backward.
