Here’s another of my designs, it’s a filament guide and cleaner for the Monoprice MP Select Mini 3D printer. I liked the idea of a filament guide and like the cleaner but there wasn’t a combo so I created one. I’ve actually re-did this and will be posted the revision shortly.
I essentially remixed a couple things to create this and added my own customizations to make it work the way I wanted and felt it needed to. The small box is the cleaner, you can just add two small pieces of sponge to the top and bottom with a little oil on it and it will clean and oil the filament as it is pulled through.
