To improve the CNC Router and not just to drill stuff, I also wanted to cut materials like cardboard, vinyl, paper, etc. Before to buy a lasercut, I did find in Internet a very interesting tool to transform the Spindle into a cutting machine. I wanted to buy the knife tool, but my spindle collet .
To improve the CNC Router and not just to drill stuff, I also wanted to cut materials like cardboard, vinyl, paper, etc. Before to buy a lasercut, I did find in Internet a very interesting tool to transform the Spindle into a cutting machine. I wanted to buy the knife tool, but my spindle collet is 8mm, and most of the tools I saw doesn´t fit on it, so I decide to make my own, and after some failed prototypes and test, I made one that until now, after several test it works just great!. The blade can be coupled in two different positions, with a cut depth of 6mm or 10mm. Component list: - 2x bearings with 8mm inner diameter - 1x 8mm x 50mm rod - 2x collar - 9x M3 30mm screws with nuts and washers - 2x M3 16mm screws with nuts and washers - Blades I spend like 30€ on components, but that´s because I bought more than I needed, just to have spare parts, and the 3D printed parts, cost like 2€ with a 2,2kg Colorfabb XT Spoon.

Add drag knife to the 3D printer upgraded version (much better than before)
