Dust Mask Filter
Project developed by User:Hschabes Add a status meter by copying the following templates (inside double curly brackets) into your page as you reach each step: status-design, status-prototype, status-deployed, status-model and status-verified....
Template:Statusboxtop Template:Status-design Template:Status-prototype You can help Appropedia by contributing to the next step in this OSAT's status. Template:Boxbottom
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
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
- PLA Filament roll --> $20.89 for approx. 330m ($0.06/m)
- Elastic --> $6.99 for 10ft ($0.69/ft) [1]
- Sock --> $9.99 for a 10pk ($0.50 per sock) [4]
- Scissors --> $4.89
Tools needed for fabrication of the OSAT
- Jellybox or similar RepRap 3-D printer
- CAD program like FreeCAD (if building from scratch)
- Slicer program like Cura (if building from scratch)
- PLA Filament of your choice
- Elastic (Or if unavailable: string, rubber bands, shoelaces, or anything that can easily be tied and adjusted to fit the mask around the face.)
- Sock (Or if unavailable: another piece of unused fabric that can fit abound the mask. Can be secured with the elastic or similar material.)
- A cutting tool (scissors, knife, etc.)
Skills and Knowledge Necessary to Make the OSAT
- If you making the OSAT from scratch, then you need to have knowledge of FreeCAD or another CAD software.
- Knowledge of Cura or a related slicer program
- Knowledge of 3D printer upkeep
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.
- Print time estimate: 3h 30m
- Assembly time estimate: 5m
- 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
- Include common mistakes/problems to avoid in building your OSAT and how to overcome them
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
References
- The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did. For example: [1]
- ↑ web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://www.eren.doe.gov/erec/factsheets/landscape.html
Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
