Alfawise U20 pen holder / porte stylo / PCB plotting

cults3d

You have an Alfawise U20 and you want to replace your extruder with a pen or felt tip pen holder to turn your 3D printer into a drawing machine, this printing is for you! This 3D model uses the fixing screws of your original extruder, all you have to do is exchange the two printing modules. There are two versions for the part that receives the pen directly, one version for smaller pens with maximum diameters of 10mm and another version for larger pens with a maximum diameter of 12.5mm. You will also need an elastic band attached between the two slides of the pen holder to allow it to spring freely without damaging the tip of the pen or felt used. Additionally, you will require a screw and nut to adjust the height of the pen and secure it firmly in place. The nut needs to be glued in position. The screw must be an M5x20 type (with 20mm length under the head and a thread diameter of 5mm) paired with a hexagonal nut of the same size, M5. You can choose from various shapes for the screw head. This model allows you to draw but also enables you to create your own printed circuit boards using a permanent marker that resists iron perchloride by drawing directly on a copper plate.
