Ender 3 Hotend Sharpie Holder for Plotting

This is a quick re-mix of the Print in Place Dial-Indicator by Turbo_SunShine to use a standard Sharpie on the Ender 3 hotend for 2D plotting. This holds the Sharpie relatively tightly so you don't need to use a spring to provide pressure. However, you do have to set the Z-Offset to make sure the Sharpie tip touches the bed at 0mm Z-height.

I would print with a brim since the surface area touching the bed is pretty small.
