I watched this video And I want to give it a try but can't find any source online of someone trying this with success. So naturally I am dubious. The other times I search about p[eople using 1.75 filament on the ultimaker I get information of doing hardware modifications to the bowden and coupler. Has anyone tried this with success? I don't want to do it all the time, I have a few ocassions where there is a filament I really want to try but the manufacturer does not make 2.85 diam
