prusaprinters

Huh? What is this?This is a modified MMU2 pulley body which has holes cut in it for a cleaning brush as used in the Skelestruder design. Why have your springs and bolts go flying when you open it if you can have the gears clean themselves?ChangelogJul 24 2019: Fixed 3mm shaft to be a better fit, widened brush holes to fit brush hubs.Jul 25 2019: No change, just re-uploaded because TV decided not to generate previews.Jan 23, 2019: Updated description; I've since printed the item and use it myself so my statement about only having printed segments for testing was outdated. Removed WIP flag.Required parts:3mm shaft19mm (3/4") disc brush, e.g. https://widgetsupply.com/product/ban14.htmlAssembly:Insert brush in slots, put shaft through, enjoy. Maybe use some M3 screws or 3mm filament to keep the shaft in place if it's loose.Notes:If there are concerns about dust falling out onto your prints, cover the slots with some tape to contain it and just clean them out once in a while. :-)Print instructionsCategory: 3D Printer Parts SummaryHuh?
