Drag knife adapter (spring mounted)
thingiverse
I wanted an adapter which allows me fixing a drag-knife to my CNC without taking the spindle out. The drag-knife adapter allows the blade to move in the vertical direction a few millimeters. Put a little sponge inside the adapter before inserting the blade, this has a spring effect which forces the blade down but is not as rigid as something fixed, it gives the knife some flexibility so it is not damaged when put in place by the z-Axis. The drag-knife I use is for the standard Silhouette desktop cutters (https://www.amazon.de/Silhouette-America-SILH-BLADE-PREM-hobbyplotter-Schneideplotter/dp/B00YU7T7NU/ref=sr_1_2?keywords=silhouette+premium+blade+3+pack&linkCode=gs3&qid=1582548532&s=kitchen&sr=1-2)
