Arm Upgrade

3D model description

Currently hundreds of people with disabilities around the world are fortunate to have a free prosthesis like this thanks to the organization ATOMIC_LAB

So, with a small grain of sand, I have designed these small pieces that are added to the standard prosthesis, significantly increasing the opening angle of the arm, facilitating control and adding a more natural and fluid movement to those who use it.

The pieces fit perfectly in both the right and left arm, you only have to take into account when printing the scalar to the same size in which the prosthesis was printed so that it fits without difficulty.

To ensure good mechanical strength, parts should be printed at the position of the .stl files.

In order for the route to be complete, an elastic band must be installed as illustrated in the last photo.


3D printing settings

The size of the pieces is very small, so I recommend a filling of more than 50%.

Wall thickness: 1.2mm

Plate adhesion: edge

Layer height: less than 0.17mm

Support: only the file called PIN.stl

Printing speed: no more than 60mm/s

Temperature: according to preferred material PLA or PETG

  • 3D model format: STL
