Abstract
This is a cotton to yarn maker. Also known as Indian charkha. Cotton obtained from the farm can be extracted into yarn with this tool. originally made of wood, Using 3D printer this tool can be made and put into use. The yarn can be used as threads in the textile industry

Bill of Materials
- 3-d printed cotton to yarn maker
- cotton
- bolt; used as a shaft for the wheel to spin
- needle to spin a yarn around it
OpenSCAD and STL files can be found here: | yarn maker
Tools needed for fabrication of the OSAT=
- MOST Delta RepRap or similar RepRap 3-D printer
- A File, only if needed to file the printed part.
Skills and Knowledge Necessary to Make the OSAT
- Basic Open Source CAD skills
- 3-D printing skills
Technical Specifications and Assembly Instructions
- Download the STL file from the link given in the Bill of Materials.
- Convert the STL to a gcode file using Cura.
- Print the files using Cura or any other related software.
- Once the part is printed, remove it from the bed.
- Assemble the different parts using bolts and nuts viz the base, the wheel, the needle stand, the wheel handle, spindle
- the wheel fits on one end and the needle holder fits on the other, use a large width needle to fit the spindle on the needle holder
- Use a cloth or thread like a belt conveyor assembly around the wheel and spindle
- using the handle on the wheel rotate the wheel to see its tightly fit or else tight the thread little more tight
- now use a cotton at the end of the needle; rotate the wheel, cotton will extract into threads on the needle
- bigger the wheel to spindle distance times the rotation can be achieved.
- The CAD and STL files are uploaded and can be modified according to the dimensions
- The print time is anywhere between 3-4 hours depending on the size of the tool and the print speed given and the assembly time is 20 min.
Common Problems and Solutions
- Each part needs to be printed seperately
Cost savings
- Cost of printing is not more than 4$.
- commercial equivalent is around 100$ https://www.amazon.com/Bigger-Charkha-Spinning-Wheel-Crafted/dp/B07JWL5XFY
