The limb sockets are held in place using a 17.5cm (7in.) piece of NinjaFlex, but you could also use elastic string.
To slice the strip part, we used Simplify3D. We recommend using the settings below or use them as reference. We 3D printed the part on a Ultimaker 2+ with a 6.mm nozzle. If you have Simplify3D, you can download our profiles below.
It's easy to modify design based on the type of amputee.
The parts where modeled in Autodesk Fusion 360. The design is public and available to download in different formats. If you'd like to use a different CAD software package, you are free to import the files and remix them.
Skirt Offset from part:
Skirt Outlines: 6
Skirt Layers: 1
Support Pillar Resolution: 8mm
To speed up printing we used a .6mm nozzle.
The arm requires custom supports added to the bottom of the arm's stocket.
The leg doesn't need any supports
We recommend using PLA material to reduce wrapping while 3D printing. The parts can be printed in different types of filament, such as ABS, PET or Nylon.
