This charcoal pen is useful in developing countries as some school supplies cannot be found and afforded in low class towns and villages. This pen was designed as a benchmark design for solving that problem! This project is in response of the OSAT project, projects that are meant to change the world for the better. It is still in development and should be tested more as well as possibly edited in its design if need be.
Bolt: 60% infill, 0.2 mm layer height, important to have high infill for maximum strength. Print Vertically for best results
Pen Shaft: 10% infill, 0.2mm layer height, Print Vertically for best results
Print Times (Varies)
Bolt and Pen Shaft Printed Together: 1 hour 55 minutes
Overall Time: 1 hour 55 minutes
Assembly Time: time ~5-15min
Take any charcoal or coal that you have available and crush it into a semi chunky powder/paste. Make sure that it retains its color so that it will show up on paper. Next take the charcoal and insert it into the end of the pen. Once this is completed, take the Bolt and begin threading it into the pen. Once the charcoal/ powder leaves the vessel, it is ready to use.
