Customizable Angled Razor Cutter

thingiverse

This is an OpenSCAD model that prints out a holder for a razor blade at a specific angle you can specify when printing. It uses a single flat razor blade: Logan 270 Matte Cutter Blade, available on Amazon at https://www.amazon.com/gp/product/B0000AE6BL/, and a bolt/nut combination allowing for depth adjustments. I rummaged through my bolts to find one that fits, likely an M2 or similar size. The nut catches on the backside so you can easily loosen the bolt to slide the blade up/down to adjust the depth. In the code, set angleOfCut = 75; to adjust for different angles in the OpenSCAD file. Then just print it. This model uses the threads.scad library for screws that stick out the back, allowing you to adjust distance to a ruler if needed (I used it to cut airplane ailerons at constant width). You may need to tap it if the threads don't print well. I printed with 3 shells and 25% infill. Note that geometry starts breaking down for angles less than about 50 degrees (where 90 is vertical). You might need to tweak the code to get razor slot depth correct.
