  1. This fills the need for a cheap aid that can help people with nerve damage. I have not found any case studies specific to this need.
  2. I am having trouble posting pictures to Appropedia again. I included a JPG attachment on my Canvas submission.

Bill of Materials[edit | edit source]

  1. PLA Filament, no alternative materials known. The print weighs 56g and the price to print is roughly $1.12.
    1. Here's the link to the Thingiverse post which includes all the files and images:

Tools needed[edit | edit source]

  1. Jellybox or similar RepRap 3-D printer

Skills and knowledge needed[edit | edit source]

  • There were no special skills required to make this.

Technical Specifications and Assembly Instructions[edit | edit source]

  1. It prints as one thing. All you'd have to do is remove the supports.
  2. It takes about 3 hours to print. It varies depending on how you modify it in a slicing program.
  3. It'll take about 15 minutes to remove the supports.
  4. Here's the link to my Thingiverse page:

Common Problems and Solutions[edit | edit source]

  • When I first printed this, the top and bottom faces didn't print correctly. To fix this, I increased the top and bottom wall thicknesses to 1. I also had to create supports on the face with the spiral on it due to overhang.

Cost savings[edit | edit source]

  • The cost of this print is roughly $1.12. The one I printed is 56g, for reference. I was not able to find a commercial equivalent, but if there is one similar to this, my cube will still likely be the more affordable option.
