on printer filament snipper (prusa mk3)

thingiverse

I created a new filament snipper using the filament guide clip and the filament clipper, combining them into one on-printer tool. This project uses two disposable blade sections, which may require reshaping with needle-nose pliers to fit snugly around the spring without any exposed blades. The brittle nature of the blade makes this process simple. To assemble the snipper, I used CA glue to permanently secure the blade into place within the button. For the spring component, I purchased a 5/16 x 1.5-inch spring from my local hardware store and trimmed it down to approximately 7/8 inch in length. Alternatively, you can use a 7mm x 19mm spring as recommended by the original filament snipper creator. In addition to the spring and blade components, I required two M3x16mm screws for assembly. When using the snipper, be aware that the filament may shoot out the side away from the printer. To address this issue, a deflector or collector could potentially be designed and added to the tool. For reference, the following compression springs may work as substitutes: 0.27-0.67 x 7x17x0.8mm with a spring constant of 1.281N (available on Amazon). I printed the filament snipper using PLA material at a 20% infill setting with supports enabled.
