This ankle brace is designed to be stronger and more versatile than other OS ankle braces available online. Most notably, this brace does not require any heat forming where most others do. With proper wrapping, this brace will allow the wearer to walk with an injured ankle. The following picture is the first iteration of the design, which has been updated to be thinner and have more cutouts to decrease print time.

Skills and knowledge needed[edit | edit source]

  • For Adjustability of this ankle brace, it is useful to have a basic understanding of Openscad.

Technical Specifications and Assembly Instructions[edit | edit source]

  1. Adjust the shell pieces of the brace to fit the user's foot as needed. Use the openscad files linked in the BOM.
  2. Print off rigid shell pieces of the brace. Use a minimum of 60% infill. For an adult, it is recommended to use 75-85%.
  3. Total print time is estimated to be 26 hours for all three parts.
  4. It takes approximately 5 minutes to wrap the foot in cloth etc and 5 minutes to lace up the brace.

Common Problems and Solutions[edit | edit source]

The most common problem is correctly sizing the brace to the user. For comfort's sake, it is better to print a bit too big and use extra wrapping inside the shell to avoid harsh contact with the rigid shell.

Cost savings[edit | edit source]

  1. Approximate printing cost for average adult male ~ $10 USD. Cost of shoelace ~ $0.50 USD. Cost of old fabric, cloth, or paper ~ free or minimal.
  2. Commercial equivalent: $60 to $80 USD Brace on Amazon
  3. Cost savings: $50 - ($10 + $0.50) = $39.50
