Abstract
- This is a mobilization wedge used by physical therapists to perform manual spinal mobilization techniques and other various exercises. The tool size is 2" X 7" X 4". This tool is normally $34.99. A conservative estimate for the price of PLA is $20/kg. 3D print cost is approximately $3.60. I created this tool using FreeCAD. The FreeCAD and stl files are attached.

- A picture of my completed print is shown to the side. As you can see, the print is incomplete and has poor print quality. This is due to a new calibration issue that has not yet been resolved

Bill of Materials
- In order to print this device, approximately 180 grams of PLA is needed.
- All CAD and STL files can be found on YouMagine from the following link: https://www.youmagine.com/designs/mobilization-wedge
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
- No special skills are needed to print this design.
Technical Specifications and Assembly Instructions
- There are no assembly instructions. This is a one piece print and it does not require the use of supports when printing. The print however does need to withstand the weight of a person. For that reason, an infill of at least 25% is recommended.
- A conservative print time estimate is 9 hours.
- There is no assembly time.

Common Problems and Solutions
- A common problem would be printing with too small of an infill percentage and the part not being strong enough.
Cost savings
- If your solution is not a low cost one then it is not really appropriate.
- Estimate your costs
- Find a commercial equivalent, cite it and put the [url in square brackets]
- Calculate $ savings and % savings
Benefited Internet Communities
- Name and add links to at least 5 using single brackets around [url name]
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.

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]].
