Pen Holder Attachment for CNC Plotter

thingiverse

I designed a pen holder attachment for my DIY CNC machine, based on the Openbuilds Acro. The inspiration behind this design came from the Parametric pen holder for CNC by yannpom. To ensure a secure hold, I used screws and heat set inserts in my design. The pen holder is also printed with the arm flat on the print bed, making it easier to print. The pen holder attachment is attached to a mini linear rail z-axis using a custom-designed mounting plate that I created. For those who want to modify the design for their CNC machine, I've included Fusion 360 and STEP files. Check out this video of my pen plotter in action: drawing Serenity from Firefly.
