Abstract
- Paragraph description of the OSAT - why is it Appropriate? What need does it fulfil? Are there case studies you have found of a technology being used successfully?
- Picture of completed print using your printer
Bill of Materials
- Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts
- Upload and link to all source files from open source CAD
- Upload and link to all STLs
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
- If you used special skill – link to relevant Wikipedia or Wikiversity articles/courses
Technical Specifications and Assembly Instructions
- 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
- Bending all of the coat hangers to a similar shape can be difficult.
- Solution: Install and glue all of the coat hangers into the Cage Ends, and then tweak the shape of the coat hangers' profile so they are symmetric.
- The Cage ends need to ride against the Side Brackets so the cage does not slide side to side.
- Solution: If they cage ends do not reach and contact the Side Brackets, edit the length of the Washer's FreeCAD model to fill the gap in between. (image below)
- Wires should be dry fit and tested to see if the hit the diagonal dowel rods. If the wires hit, re-bend them or shorten their length. (image below)
Cost savings
Part Cost Total $19.62
- 30x Coat Hangers (or equivalent wire) $4.32
- 2x 5/8"-36" Dowel Rods (or equivalent stick) $8.58
- Broom Handle (or equivalent handle) $3.32
- 3D Print's Material Cost $3.40 (assuming $20/kg of PLA)
Prices for non-3D printed parts are based on the items purchased for the prototype. Recycled wire and wood could be substituted in place of store purchased items.
Commercial Equivalent
Savings
- Compared to the cheapest Walmart gather, the 3D printed ground gather brings the price down by a third.
- If recycled wood rods and wire were used in place of the purchased coat hangers and dowel rods, the price of the 3d printed ground gather could be decreased further.
Benefited Internet Communities
- Golf
- Golfers or driving ranges could make cheaper golf ball collects than the current ones on the market.
- Tennis
- Tennis players could creating their own ball collector instead of purchasing an expensive one.
- Nut Collecting
- Anyone with a tree that produces nuts might be interested in harvesting them, but they do not want to purchase an expensive Nut Wizard.
- Windfall Apples
- Apples that fall on the ground, windfall apples, can be collected and used for cider or animal feed.
- Acorn Removal
- Removing acorns so as not to cause accidents with lawn mowers, or remove them to prevent them from sprouting.
