3d printer parts. Answered

Hello. I am a high school freshmen, and I am on a robotics team. We own a Dimension 3d printer, however I am not able to use it for personal projects. I am a CADer and would love to find parts or broken 3d printers to where I can build my own functioning 3D printer. Being 15 I do not have sufficient funds to where I can afford 3d printers. Any type of help would be amazing! If you have any information, please let me know. Thank you! -Evan
