Scissors using 18 mm snap-off blade

thingiverse

Part of a research initiative focused on tools utilizing snap-off blades and three-dimensional printing technology can be accessed via the GitHub repository https://github.com/jonnor/projects/tree/master/snapblade-tools . It functions adequately for medium- and thick paper, as well as cardboard. The device performs poorly with thin paper and other soft or flexible materials when attempting to utilize a shearing motion; however, its blades are sufficiently sharp that they can be cut simply by slicing through. Additionally, it has been successfully tested on cutting small electronics wires, small plastic pieces, including 2.85 mm PLA filament. Vitamins required include: • Two 18mm snap-off blades • One M5 locknut • One M5 bolt measuring at least 16mm in length • Two M5 washers • Printing two components of the simple-scissors STL file (approximately 15-20 minutes per component) Prior to assembly, three pieces from each blade must be snapped off and then inserted into the printed part. Potential improvements include: • Angling the blades slightly towards each other • Developing a mechanism that enables clamping down to tighten the blades together
