on printer filament snipper (prusa mk3)

thingiverse

I remixed the filament guide clip and the filament clipper to make this on-printer filament snipper. It uses 2 sections of a disposable blade - you may have to reshape it with needle nose pliers so no part of the blade sits on the spring. The blade is brittle so it's easy. I used CA to permanently retain the blade into the button. I bought a spring at a local hardware store. 5/16 x 1.5 inches - I cut i down to about 7/8 of an inch. You can use a 7mmx19mm spring as suggested by the original make of the filament snipper. And you will need 2 m3x16mm screws. The filament will shoot out the side away from the printer. Maybe I or someone can make a deflector or a collector. these springs might work: https://www.amazon.com/0-27-0-67-7x17x0-8mm-1-281N-Pieces/dp/B07FFRVXB8/ref=sr_1_fkmr3_1?keywords=compression+spring+7mm19mm&qid=1555101905&s=gateway&sr=8-1-fkmr3 I printed in PLA at 20% infill with supports. https://youtu.be/8kU6ocoKqCw
