Drag knife and pen mount for CNC 3018
thingiverse
This is a precision-made drag knife holder designed specifically for CNC machines like the 3018 model. The primary objective was to create a versatile holder that accommodates small variations on the Z-axis, ensuring seamless operation even with an uneven bed without requiring any modifications to the CNC system. Files marked "v2" have been optimized for added rigidity and stability. In contrast, version "v3" boasts enhanced stiffness, making it ideal for cutting through thick materials with ease. To achieve optimal results with version "v3," follow these print parameters: - Wall Line Count: 5 - Top/Bottom Layers: 3 - Layer Height: 0.2mm - Infill Percentage: 30% (Note: The author recommends using Quarter Cubic infill for maximum efficiency) A notable feature of this design is the undersized hole intended for the knife holder. To ensure a precise fit, simply submerge the aluminum knife holder in hot water and carefully push it into place until it's snugly seated.
