Ender 3 Pro Pen/Wood Burner Holder

cults3d

These items are attached to an Ender_3_Pro (and probably similar 3D printers) in place of the extruder assembly to hold other tools. The drawings were made using Tinkercad and ideas from several other Thingiverse tools. It is still a work in progress and is the first Thing I am publishing here and I hope to add more information, pictures, or files later. The Gcode files are what I used on my Ender_3_Pro with cheap PLA filament. The quality was good enough for me but you probably want to slice the models yourself. The holder for wood burner is not perfect but was made to hold a wood burning tool. This was held in place with a rubber band but the tip (I used a round point tip) tended to unscrew itself during use. The holder for pen was designed to hold a pen, pencil, or marker to use the 3D printer as a plotter similar to pascalmakes plotter mod but is closer to the original extruder location so more of the bed can be used. The Gcode files for using the printer as a plotter were made using Inkscape and various extensions to adapt the code to raise and lower the tool instead of turning a laser on or off. I also added custom code at the start to allow adjusting the position and height before continuing. This is not ideal because it is hard to run again in the exact location but it is what I have been using mainly to set the height of the tools. I sometimes will use the babystep the Z axis option for adjusting the height during printing. This is especially needed if using a pencil which will wear down as it writes. Also, the firmware of the Ender_3_Pro I used needed to be updated to allow G2 and G3 ARC moves. Use this code at your own risk. It is easy to crash into your bed or exceed the axis limits when you are trying to use the 3D printer to do things it wasn't originally intended for.
