Pen Plotter for Flyingbear P902

thingiverse

I created this pen holder specifically to attach it directly to the original carriage of my P902 printer. To assemble it, you'll need two M3 screws, attached from below as shown in the photo. You also have the option to secure the pen's position with additional M3 screws. Note: The pen diameter ranges between 9 and 8 mm, varying slightly depending on its proximity to the spot where it's placed. I used a Faber Castell Multimark 421-S Permanent Marker for this project. UPDATE: I've since added a screw support, allowing me to print PCBs in an inverted orientation.
