3018 CNC Drag Knife Holder

thingiverse

I needed to attach a drag knife to my 3018 cnc (pro) without constantly removing the spindle motor. The knife holder is working exceptionally well. The spindle-blocker functions perfectly, but its appearance leaves much to be desired. Feel free to reimagine and enhance it or invent something entirely new that surpasses it! I printed the "blocker STL" and used a piece of 4mm plywood to cut the "blocker SVG". I secured it on the back of the plastic part using 3mm screws. To minimize any movement, I trimmed the noses so it fits snugly on the spindle holder. The drag knife (12mm body diameter) was purchased from [here](https://s.click.aliexpress.com/e/_dTunLvW).
