This is only pen holder for original Prusa Mini Plotter Addon V2.
If you miss information how to create your first drawing, look here: Prusa Mini Pen Plotter. With my penholder you can use 2 mm more space. You can use in the Inkscape plugin settings (Coordinate system & Transformations tab) the size 142 x 180 mm and offset -38 mm.
The author remixed this model.
