SummaryJust a very simple holder for MK 10 8mm and 10mm nozzles. Im putting new on the top step and cleaned out nozzles on the bottom. I hope it is useful to someone. Thanks Ive since added a couple of resized blocks to 10mm holes. One with deep 19mm holes. I also added a copy of th original but with 3d text that says MK-10Print SettingsPrinter: FlashForge Creator ProRafts: NoSupports: NoResolution: MedInfill: 50%Notes: Its nicer to make it a denser infill. That gives it some weight.
