LEGO pen mount for large treads

thingiverse

The original project involved attaching a ballpoint pen to LEGO large treads, creating a drawing bot with an XY cartesian system and motors capable of producing intricate patterns. Although photographs of this invention were not captured before it was dismantled, the concept demonstrated the principles of design using the pen's movable inner workings for pressure on paper while remaining secure in the adapter. The key idea was to mount the pen onto LEGO treads, emphasizing the importance of the innovative approach.
