SummaryWhen I need to change a nozzle on my FlashForge Creator Pro I used to wedge a screwdriver between the two cooling blocks so that the one I was working on wouldn't move. This didn't really work that well so I made this tool to keep them in place while I unscrew the nozzle. Let me know if this fits your machine. Thanks for checking it out.Print SettingsPrinter: FlashForge Creator ProRafts: NoSupports: NoResolution: MedInfill: 85%Notes: I used an Infill of 85% to make this pretty solid and strong.
