Filament weld joint trimmer

thingiverse

This tool will clean up the joint of welded filament. It requires the addition of 4 utility knife blades, and 4 screws (M3, #5, or #6. 10mm or less in length. it works by first manually trimming the joint with flush cutters and then slipping the filament into the slot and running the trimmer back and forth across the joint while twisting the tool around the filament. you must start with a solid and straight joint, if the joint is bad, you will quickly know. I have only used this with PLA. You may need to tap the holes if using machine screws. The holes are aligned with the blade, be sure to pay attention to which hole you are using.
