Aya's forearm walker attachment

A forearm walker attachment,

for a standard reverse walker,

adapted to the user.

Print the two STL parts (for the right and left hands) using a 3D printer.

Recommended: PETG filament, Print in high infill.

Cut two pieces of MDF (Medium-Density Fiberboard) according to the specified dimensions.

Drill two holes in each surface of the MDF pieces.

Place two nuts (of a bolt) inside each of the drilled holes, and glue them to the MDF.

Cut polyethylene foam according to the dimensions of the MDF pieces,

and glue it onto the MDF surfaces.

Prepare a suitable piece of vinyl fabric, that will wrap around the polyethylene foam and MDF together.

Wrap the fabric around the assembled MDF and polyethylene foam (similar to upholstering a chair),

using glue spray and a staple gun to secure it in place.

Attach the padded surface you created to the 3D printed parts using screws,

by screwing them through the print into the polyethylene foam.

Cut two strips, one for each hand (sized for the forearms).

Cut two pieces of velcro for each strap, one male and one female.

Sew the velcro pieces onto the ends of the straps.

Thread the straps through the destined areas of the 3D printing model.

Cut a silicone tube to the required size.

Thread the silicone tube into the 3D print.

Connect the 3D print to the front tube of the reverse walker,

using the existing pin and screw it into the corresponding hole.

Take a metal clamp and thread it between the 3D print and the reverse walker tube.

Tighten the metal clamp securely.

Congratulations! Your forearm walker attachment is now ready to be used.
