SummaryJust simple linear bearing/slider to replace wobbly ones in your printer. After you print it you should run an 8mm drill through it backwards. If the bearing does not slide smooth, try using drill again. I used silicone oil as lubricant. This bearing is a replacement for Sunhokey prusa i3 short bearing.Print SettingsPrinter Brand: RepRapPrinter: Prusa i3Rafts: Doesn't MatterSupports: NoResolution: 0.3mmInfill: 5%Notes: Print it in PLA or even better Nylon.
