Abstract
The Drop Spindle is an ancient tool used for spinning fibers such as wool, cotton, flax, and hemp into yarn, without the need for a large, expensive, and complex spinning wheel. Traditionally Drop Spindles are made out of wood with with a notch, groove, or metal hook on the end for securing the yarn. The drop spindle provides the tension necessary to spin yarn and provides a convenient way to introduce twist into the yarn as well as a place to wind yarn as it is being spun. Spun yarn can be woven, knitted, or crocheted into a multitude of fabrics or garments that can keep oneself warm or be traded for goods and services.
- Picture of completed print using
Bill of Materials
- PLA Filament, about 20grams
- Marine Epoxy Stick ~$3.39 per container. Only need 1/16 of container.
- Alternatively any super glue or epoxy will do. Natural gums and saps that harden may work as well
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make and Use the OSAT
- Basic Usage of 3D Printer
- Tutorial on Using a Drop Spindle
- Tutorial on Finishing Yarn and Wrapping Skein
l
- Provide directions for print/assembly - be detailed enough in your “how to” to ensure that someone could construct the device from your description. Consider the elegance of IKEA like instructions.
- Include print time estimate
- Include assembly time estimate
- Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
- Consider video if appropriate

Common Problems and Solutions
- Rod is too large to fit through hole in disk
- Enlarge Hole in disk with pen knife
- Make Rod slimmer using Pen knife
- Be sure not to over do it, ideally you will have a press fit.
- Rod is too small to stay in place in disk
- Use Super Glue, 5-Minute Epoxy, or Marine Epoxy puddy to secure disk to rod
Cost savings
- If your solution is not a low cost one then it is not really appropriate.
- Estimate your costs
- Find a commercial equivalent
- Calculate $ savings and % savings
