3d Plotter

This is an attachment for the compact extruder I already published. It is a holder for a pen, pencil or crayon to use your 3d printer as a plotter.
The way is designed is to be permanently mounted on the carriage but can be removed as well with just 4 screws.
The purpose of this was to draw PCB masks directly on copper laminate boards for etching, but you can draw anything you like and use the 3d printer slicer to generate the g-code to plot your drawing.
There is a little bit more to do than normal 3d printing, but once you set up the parameters it is pretty easy.

For pcb etching is easy because pcb softwares allow to export the pcb layout in dxf format, then you can extrude the drawing using a CAD program to the minimum height your slicer accept and add a few g-code parameters to send to the printer before it starts to print.
I extrude it to 0.3mm but if you make it higher the only thing that can happen is that after drawing the first layer, the print head will lift for the se
