Drag knife holder for MPCNC

cults3d

UPDATE: This is likely an ill-conceived design since it removes the blade-length restriction feature of the holder housing. This Roland-style drag-knife holder mount is specifically designed for use with the Mostly Printed CNC. A plastic spring presses down on the tension button located at the top of the holder, providing a secure hold. To enhance tension, you can customize the spring by making it thicker or printing it in PLA instead of ABS. The strap requires M3 screws for attachment. This unit is composed of two main parts that can be combined using glue and/or a small wood screw. There are join screw holes on the side to facilitate this process. However, before joining the parts together, insert M3 nuts into the nut traps to ensure a smooth assembly.
