A filament guide that just slides into the rail of an Ender 3 Pro, deep enough so that it doesnt budge IMPORTANT: this design NEEDS a ball bearing You can either print it or buy a 604zz ball bearing The ball bearing measurements are: Inner diameter: 4mm Outer diameter: 12mm Width: 4mm Also, i used a 4mm cilindrical wood piece as a holding pin, but i added a file for the holding pin, just in case
