CNC drag-knife / vinyl-cutter holder for Graphtec CB09 style drag-knife

thingiverse

This is a cradle for the GraphTec CB09 style drag-blades, designed to fit snugly within a 1/4-inch CNC router/spindle chuck.\r\nThese types of drag-blades can be purchased affordably on Amazon and other online retailers, typically costing around $15 each, often including multiple blades.\r\n\r\nI recommend printing in PETG (this material is less prone to brittleness) using all perimeters (ensuring a solid build .. I set 30 perimeter walls, which is more than sufficient).\r\n\r\nThe drag-blade should be pressed firmly into the cradle, and then the cradle can simply be clamped into the 1/4-inch chuck just like any router bit.
