Filament Sharpener -- 1.75mm
cults3d
I was having trouble with my filament getting stuck on the starting connector of my Bowden tube, so I decided to try something new. I picked up a pack of inexpensive pencil sharpeners from a dollar store thinking maybe one of them would fit the bill. However, they were all too large for the job. Undeterred, I turned to my trusty 3D modeling software, SketchUp, and designed my own custom tool that perfectly fits the blade they use. After making a few tweaks during the printing process, it finally worked like a charm on its third revision.
