I just finished building the MMU3 that my brother and girlfriend bought me for Christmas! And, the instructions beg you to sharpen the filament to a point. Well, how do you achieve this? I saw you guyses' ideas which usually involve a hand-held pencil sharpener (any of which I do not own). But, I do have an electric, tabletop pencil sharpener (that happens to be made by Boston). And, so I scanned a sharpened pencil on my printer/scanner. And, then I imported the scan as a reference in Blender. I quickly modeled it and printed it. After several rounds of printing, testing, and making slight modifications, I felt that this version (which has a 2.4mm filament channel) was perfectly acceptable to post here for you nice people! I printed it in 2 colors because why not? The tip gets dirty from its normal use in a pencil sharpener. So, I wanted the tip to be dark to hide the ugliness. But, I wanted the body to be brighter and more inspiring. It is totally fine to print in one color, though. I almost forgot!... I use a store-bought foot (stomp) power switch to control the power to the pencil sharpener. Otherwise, the sharpener would be grinding away the entire time that the adapter is inserted! I hope you enjoy this model and give me lots of notes! hugs and kisses, Beau.
