Hotend parts for the Prusa Mini with E3D Revo Micro to enable mounting a pen and using as a pen-plotter. You will need M3 heatset inserts and M3 screws to secure the pen or just use a slightly bigger screw and you should be ok.

The author remixed this model.
I have mashed these three models together to create this model and added holes for M3 heatset inserts.
