Charcoal Pen: Maker Information

Project developed by [Max Pletcher Mackspletch (talk) 10:07, 5 December 2016 (PST)]

This Open Source Appropriate Technology has been designed but not yet tested — use at your own risk.

This Open Source Appropriate Technology has been prototyped.

Abstract

1. 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.

• No Special Skills or knowledge required

Technical Specifications and Assembly Instructions

1. Print Settings
   1. Bolt: 60% infill, 0.2 mm layer height, important to have high infill for maximum strength. Print Vertically for best results
   2. Pen Shaft: 10% infill, 0.2mm layer height, Print Vertically for best results

1. Print Times (Varies)
   1. Bolt and Pen Shaft Printed Together: 1 hour 55 minutes
   2. Overall Time: 1 hour 55 minutes

1. Assembly
   1. Assembly Time: time ~5-15min
   2. 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.

Common Problems and Solutions

• Make sure to print the bolt with a high infill for maximum strength. This helps break down the charcoal as well as keep the pen in shape.
• If there is a file on this project is unsatisfactory to your liking, please edit the attached files to your liking and upload to this page!
